Adopt elide reconcile API + schema feature; collapse mirrors; docs refresh

[martsokha]

Summary

Pulls upstream elide twice in this branch (0ca39cf3 → 416f3165), absorbs the two breaking changes that came with it, deletes the duplication those changes made obsolete, and rewrites the docs around the new toolkit/runtime split.

Reconcile API adoption

Upstream collapsed the dedup pipeline calibrate → fuse → resolve → filter into calibrate → reconcile → filter. One ReconcileLayer<G, R> covers both passes via two configurations:

• same_label(Merging<scoring>) — fuse same-label overlaps (scoring: Max or NoisyOr; Mean is gone).
• cross_label(Structural<tiebreaker>) — break cross-label ties (HighestConfidence or LongestSpan).

Wire mirror in nvisy-core::plan::deduplication:

• FusionStrategyParams → MergingStrategyParams (MaxConfidence → Max; Mean deleted; NoisyOr kept).
• ResolutionStrategyParams → TiebreakerParams (variants unchanged).
• DeduplicationParams.fusion → merging; .resolution → tiebreaker.

Adopt elide's schema feature; delete nvisy-core::schema

Upstream now derives JsonSchema on every domain type behind a schema feature. Eight mirror types in nvisy-core::schema are now redundant duplicates of the elide canonical types — same field names, same wire format. The whole schema module is deleted (~250 LOC) and call sites import the elide types directly:

Mirror (deleted)	Replacement
ColorSchema	elide_core::primitive::Color
BoundingBoxSchema	elide_core::primitive::BoundingBox
PointSchema	elide_core::primitive::Point
PolygonSchema	elide_core::primitive::Polygon
LabelSchema	elide_core::entity::Label
LanguageTagSchema	elide_core::primitive::LanguageTag
TimeSpanSchema	elide_core::primitive::TimeSpan
WaveformSchema	elide_core::modality::audio::Waveform
OperatorIdSchema	deleted unconditionally (no callers)

Engine state derives JsonSchema

Now that elide's schema feature is on, Entity<M> is schema-able. The engine's persistence types follow: EntityRecord<M> (generic bound on M::Location + M::Data), Run, RunState, RunDocument, RunDocState, DocBody, StartBatch, DocumentInput. Run's Timestamp fields get #[schemars(with = "String")].

Server DTO collapse

Two response-side DTOs whose engine equivalents now derive JsonSchema natively are gone: ResourceRefDto and ModalityDto. The request-side ResourceRef mirror module is also deleted. Handlers import nvisy_engine::runs::{ResourceRef, ModalityKind} directly.

The remaining response-side DTOs stay because they do real shape-flattening (provenance drop, HipStr→String, BoundingBox→flat {x,y,width,height}), not just JsonSchema-bridging.

Docs refresh

The four toolkit-side white papers (README, DETECTION, INGESTION, REDACTION) now live in elide/docs and are deleted here. DEVELOPER.md is also deleted. The four remaining docs are rewritten runtime-first:

• README.md — runtime overview in the same white-paper style as elide's README; positions the runtime as the engine wrapping the toolkit (tenancy, durable governance, two-phase review).
• PIPELINE.md — runtime-specific lifecycle: the run as the unit of work, two-phase analyze→review→apply, files as the input/output interface, artifact + override identity, policy/context resolution, failure + cancellation.
• COMPLIANCE.md — composite audit (toolkit provenance + runtime attribution), the four decision provenances the two-phase pipeline surfaces, retention boundary, multi-tenant isolation, what the runtime does and does not underwrite.
• INFRASTRUCTURE.md — deployment shape (one process, one data directory, no service deps), the six persisted keyspaces, operational primitives, scaling by sharding actors across instances, what the deployment must provide.
