Vito cbc53ee9f1 feat(resolver): trace multi-stage chains through pass-through nodes (#308)
* feat(resolver): trace multi-stage chains through pass-through nodes

The inspection resolver (server and local Inspect) now compares a sampler
with the earlier sampler its latent continues through image-space
pass-through nodes: decode, image filter, model upscale, scale and encode,
listed in a new validated `lineage` section of the semantics table. Equal
prompts resolve (hires-fix, refiner); different prompts are
multistage-differs. A later stage whose positive adds conditioning to the
shared base prompt through an additive composite (ConditioningCombine or
Concat) keeps the base pair, the text legacy linked (three-stage Flux).
Image-edit batches stay ambiguous and run-time text stays untraceable.
Ingestion keeps the default profile (D1).

A card no longer shows a seed when the inspector names a chain stage
whose seed differs from the parser's pick.

* feat(resolver): leave out run-time PromptManager parts, labelled

Maintainer option A: when a PromptManager prepend_text or append_text is
fed directly by a node whose output is decided at run time (LoraManager's
TriggerWord Toggle, now a runtime class, or PromptSearchList), the prompt
resolves to the node's own text, as legacy showed. The side's source is
runtime-parts-omitted and the resolved reason says that text added at run
time, such as trigger words, is not included; the prompt block shows that
line (D-NEW-R1). The toggle's output is never computed. Literal and
traced parts are combined as before; an indirect run-time part, a run-time
main text or an unknown feeder keep their outcome. The browser port
changes identically. Ingestion is unchanged.

* fix(resolver): keep run-time and added-conditioning labels honest

A text that left out a run-time PromptManager part is now labelled when
any node on its traced path omitted it, so the label survives encoders,
concatenations and chained PromptManagers. Comparisons include what a
text leaves out, so a partial prompt never equals a complete one: a
branch with trigger words and one without stay ambiguous, and such
stages are multistage-differs. Only classes listed as run time are left
out.

The added-conditioning floor labels its positive (D126, "Conditioning
added at a later stage is not included."); the run-time line is D125.

A card hides its seed only when the stage the inspector names reads a
different seed than the parser; an agreeing seed is kept, as on main.
The browser port moves its lineage, latent and part helpers into
local-resolver-stages.mjs, keeping parity.

"""Multi-stage chains joined through image-space pass-through nodes.
A hires-fix or refiner run decodes sampler A's latent, filters, upscales and
scales the image, then encodes it again for sampler B. The semantics table's
``lineage`` section lists the nodes through which the latent or image carries
on unchanged in kind. When B's latent descends from A only through those nodes
and the stages share one pair, the chain resolves to it. A last stage that adds
conditioning to the base prompt (ConditioningCombine of the base and a style
trigger) keeps the base pair: the floor legacy linked. Everything else stays
ambiguous or unresolved. Ingestion (the default profile) is unchanged (D1).
