feat(workspace): complete shared inspector and collection viewer (#224)

* feat(inspector): expose bounded physical file evidence

* fix(inspector): distinguish ambiguous saved associations

* feat(inspector): derive conservative generation facts

* fix(inspector): guard fact ancestry and inspection state

* feat(inspector): share complete file details and exports

* fix(inspector): preserve fact states and touch targets

* feat(viewer): navigate the loaded media collection

Refs #216

* fix(viewer): refit after current stage geometry changes

Ref #216. Observe the current media stage after readiness and wrapped title changes without rebuilding focused controls or resetting transforms at unchanged dimensions.

* feat(viewer): add lifecycle-safe slideshow and media preferences

* fix(viewer): resume gallery continuation after close (#216)

* fix(images): guard source recovery and wrap viewer actions

Clear stale root and folder intent, cancel old pages, and wait for current source discovery before loading a refreshed collection. Preserve safe retry through failed, superseded, and disposed discovery.

Wrap narrow viewer footer actions and wait for measured gallery viewport settling in responsive checks. Refs #216; addresses PR #224 review.

* test(viewer): await gallery layout after viewport changes

Require actual inner, root client, and document widths to agree after each responsive-case viewport and CSS zoom transition. Keep the existing exact frame, overflow, focus, and coarse target assertions unchanged.

Observed PR #224 CI initial mobile resize at537px before pending card relayout settled to356px. Refs #216.

 - Shared role-aware sending and the physical-file prompt inspector merged in [#203](https://github.com/ComfyAssets/ComfyUI_PromptManager/pull/203) and [#206](https://github.com/ComfyAssets/ComfyUI_PromptManager/pull/206).
 - The native Prompt Library merged in [#210](https://github.com/ComfyAssets/ComfyUI_PromptManager/pull/210) for [#208](https://github.com/ComfyAssets/ComfyUI_PromptManager/issues/208): one positive parent, saved negative variants, full selected text and a shared filtered image gallery. It does not invent chronological runs from counters or scan dates.
 - [Durable history storage](prompt-history-storage.md) records job attempts and outcomes from [#212](https://github.com/ComfyAssets/ComfyUI_PromptManager/pull/212), frozen prompt contexts from [#213](https://github.com/ComfyAssets/ComfyUI_PromptManager/pull/213), and observed run-owned output locators from [#214](https://github.com/ComfyAssets/ComfyUI_PromptManager/pull/214). Those locators do not verify file bytes or establish gallery-image associations. That association contract and the chronological execution timeline remain pending under [#209](https://github.com/ComfyAssets/ComfyUI_PromptManager/issues/209).
-- [#215](https://github.com/ComfyAssets/ComfyUI_PromptManager/issues/215) brings the shell, Images and natural-height Prompt Library presentation into the approved geometry and themes while retaining their existing operations. Full inspector/viewer parity remains pending under [#216](https://github.com/ComfyAssets/ComfyUI_PromptManager/issues/216); this presentation slice does not establish whole-application parity. Tagging/review, System consolidation and the remaining organization capabilities continue under #196.

[#216](https://github.com/ComfyAssets/ComfyUI_PromptManager/issues/216) adds the shared current-file inspector with exact generation facts, scoped provenance, raw/download evidence and loaded-collection viewer controls, including a slideshow that pauses at native video. This delivery does not establish whole-application parity, change the default entry point or constitute a release. Recorded chronological run/context browsing continues under [#209](https://github.com/ComfyAssets/ComfyUI_PromptManager/issues/209); image tagging/review, System consolidation and remaining organization capabilities continue under #196.
