fix(workspace): revalidate served pages and static files on reload

The workspace pages and every file under /prompt_manager/js and
/prompt_manager/lib went out with no Cache-Control and no validator.
ComfyUI's own cache middleware only fills a missing Cache-Control for
paths ending in .js or .css, so the workspace's .mjs modules got no
header at all, and after an update the browser could keep running old
modules until a hard refresh.

Every page and static file now carries Cache-Control: no-cache and a
weak ETag over its bytes, and a request that already holds that version
gets a 304 without a body. A normal reload picks up new code and stays
cheap when nothing changed.

Closes #478

+**D153** (maintainer ruling 2026-10-28: the star is only for favorites; the concept keeps
+a 1–5 rating): the workspace shows and edits no prompt rating. The concept's rating
+appears in four places, and production draws none of them:
+
+- Library cards: the concept's footer reads "★★★★★ · Used today"; production reads only
+  the last use (amends D23). `library-concept.spec.mjs` takes the stars and their " · "
+  out of the concept page itself before measuring (`dropConceptRatings`), so the footer
+  facts are compared at production's width; it first checks that every concept card had
+  them.
+- Sort: the concept's "Highest rated" is not offered on Images or the Library (amends
+  D14); the comparisons drop it from the concept's options. A saved view or a Library
+  visit that still names `sort: "rating"` opens on Recently added; the server keeps such a
+  view as it was stored.
+- Editor (New prompt, Edit recipe metadata, Create text revision): no `#recipe-rating`
+  "Rating" select; `library-editor-canonical-comparison.mjs` `mapConcept` drops the
+  concept's Rating field. The editor never sends `rating`. An edit sends only changed
+  fields, so a stored rating stays as it is; a new prompt and a text revision create an
+  unrated positive (the revised prompt keeps its own rating; the legacy admin page shows
+  the revision as unrated). A reuse that leaves metadata unapplied compares title,
+  category, tags and notes only. The edit token still covers `rating`, so a rating
+  changed on a legacy page while the editor is open is an ordinary metadata conflict
+  whose review shows no visible difference.
+- System > Statistics: no "Avg. rating" column and no "Rated images" total (amends D96);
+  `system-concept.spec.mjs` maps the concept's table without that column.
+
+Data and API are unchanged: the `rating` column (`CHECK` 1–5), `PUT
+/prompt_manager/prompts/{id}/rating`, `rating` in Library, Images and statistics
+answers, and the server's `rating` sorts. The legacy pages keep their ratings until the
+cutover (#334). Favorites (the image star) are unchanged.
+
+Tests: units `tests/js/workspace-library-editor-state.test.js` (a prompt rated 4 edited
+and saved keeps 4, no `rating` in any body, no rating field),
+`workspace-library-state.test.js`, `workspace-images-state.test.js`,
+`workspace-saved-views.test.js`, `workspace-system-overview.test.js`,
+`workspace-library-format.test.js`; browser `workspace-library-editor.spec.mjs` (the

+**In the monitor.** An output whose workflow has no positive PromptManager node
+(`_find_prompt_from_metadata` says `foreign`) used to be logged and skipped. It now
+goes through the same ladder with the `MONITOR` policy (`utils/foreign_runs.py`, the
+handler's `_ingest_foreign`, `_recheck_foreign`, `_store_foreign`):
+
+- **At settle.** The ladder runs without history. Certain (`pair` or `positive`): the
+  prompt is stored and the file linked at once. `history` (an undecided graph inside
+  ComfyUI's output folder): the file is registered in its own waiting set, then the
+  ladder runs again at once with the file's recorded output, because the run may have
+  been sealed before the file settled. When that lookup finds a record, its answer is
+  final: certain is stored, anything else is logged "No certain prompt for <file>;
+  left unlinked" and the file stops waiting (no seal is coming). When it finds none,
+  only the inspector's or the recorded saver's answer is stored; anything else (the
+  legacy floor included) keeps waiting for the re-check. Anything else at the first
+  pass is logged "No certain prompt for <file>; left unlinked".
+- **After the run ends.** When the run's outputs are sealed, each waiting foreign file
+  gets one re-check (`ForeignRecheck(reference)`) with the sealed output reference,
+  so history is asked with the spelling it recorded (a Windows folder whose case
+  differs from the disk still links). Not certain: "No certain prompt for <file>
+  after its run ended; left unlinked". An ambiguous inspector answer is never given
+  the legacy floor in the monitor (D-Q3); an untraceable one still is.
+- **Waiting sets.** `_awaiting_foreign` and `_foreign_due` sit beside the keyless sets
+  with the same bounds (1000 files, one hour) but are separate, so a large foreign run
+  never evicts a waiting keyless file. An expired entry is logged "No recorded run
+  for <file>; left unlinked", an evicted one (waiting or due) "Too many files wait for
+  their run; <file> left unlinked", both after the lock is released. A due re-check
+  is dropped only when it was scheduled, never a newer reference for the same file. `awaiting_foreign()` lists them;
+  `shutdown()` and `close()` clear them, and a closed handler re-checks nothing.
+- **Store.** One write through `survive_switch` (rerun after a Move library): a pair
+  through `ingest_resolved_pair(..., marks=RUN_MARKS)`, a positive through
+  `store_scanned_prompt_or_raise(..., RUN_MARKS)`. A created prompt carries category
+  `scanned`, tag `auto-scanned` and the note `Saved from a workflow run: <file>`; a
+  file linked to another prompt is `conflict` and keeps its link. Logged at info
+  "Foreign run: <status> prompt <id> for <file> (<source>)"; a failure is logged and
+  the file stays unlinked.
+- **Never.** No tracker FIFO entry is read or consumed, nothing is counted (run count
+  stays 0, no `last_used_at`), and nothing is queued for Needs review.
+- **The setting.** `GalleryConfig.SAVE_FOREIGN_RUNS` (`gallery.monitoring.
+  save_foreign_runs`, default true, only a bool applies) is read for every file, at
+  settle, at the re-check and again just before the store, together with
+  `MONITORING_ENABLED`: either saved off stops foreign writes at once (the running
+  observer watches until a restart, D128); off logs "No PromptManager prompt in
+  workflow, skipping image" as before. System › Sources & scans "Save prompts from other workflows" (D158)

+"""Repair the links the old scan gave foreign dataset files (#247), on review.
+
+Before #247 the output scan linked each file of a foreign run (a workflow
+with no PromptManager node) through the legacy parser, so every file of a
+shared-prefix dataset run got the first branch's text. Recorded history
+knows which save node wrote each file; the shared ladder
+(``utils.file_prompt.decide_file_prompt``, scan policy) uses it
+(``recorded-run``) to name the right branch. This tool judges every
+``generated_images`` row of a file whose recording runs all have no
+PromptManager context:
+
+``relink``  the ladder names a positive by the recorded saver, and its text
+            is not the linked prompt's
+``keep``    the recorded saver or the inspector names the linked prompt
+``skip``    anything else (file gone, no single recorded saver, ambiguous,
+            the legacy floor or another step decided)
+
+Dry run (the default) judges a copy of the database (SQLite backup from a
+read-only connection) and writes a JSON plan and a Markdown list beside it
+(``<plan stem>.list.md``). It also rehearses the apply on a second copy, to
+list the prompts that would lose every link with their remaining
+references. Deleting those is OFF unless the dry run is given
+``--delete-orphans``; the choice is recorded in the plan and rehearsed on a
+third copy. The library is never written.
+
+``--apply <plan.json>`` (ComfyUI stopped), only on the library the plan was
+made from (its real path, recorded in the plan):
+
+1. refuses unless ``--comfyui-dir`` holds ``main.py``; refuses while a
+   ``main.py`` runs from it, anything listens on ``--port``, or any other
+   process holds the library, its ``-wal`` or ``-shm`` open
+   (``tools/comfyui_stopped.py``; without /proc only with
+   ``--i-stopped-comfyui``). ``--rehearsal`` skips the process and port
+   check, never the open-file check, and never for that folder's library;
+2. saves ``<db>.pre-247-repair_<stamp>`` (or into ``--backup-dir``), never
+   over an existing file, and refuses unless the backup passes
+   ``integrity_check`` with the library's counts. Opening the library must
+   not change its schema (a newer checkout's migration): run the tool from a
+   checkout at the live code version. The running check runs once more just
+   before writing;
+3. in ONE ``BEGIN IMMEDIATE`` transaction: re-judges every planned row and
+   refuses on any drift (row moved, prompt text changed, file changed, target
+   stored since), creates the target prompts that do not exist (category
+   ``scanned``, tag ``auto-scanned``, note ``Auto-scanned from <first file>``),
+   points each row at its target and drops its pair links (they named the old
+   positive). A file that already has a row for the target keeps that row and
+   loses the wrong one (UNIQUE(prompt_id, file_path)). Orphans are deleted only
+   when the plan chose it and each is still unreferenced.
+
+Any failed check rolls everything back and exits 2. Before/after table
+counts, ``integrity_check`` and ``foreign_key_check`` are printed.
