Implement CE-WP-0003 T01-T08: form binding + visual guide overlay

Browse Source 
T01 EvidenceLink/EvidenceSet types
  - src/shared/evidence-link.ts: status (§2.4), relation (§2.5), target
  - src/shared/evidence-set.ts: ordered group + activeEvidenceItemId
  - enum-conformance test parses SharedContracts.md and asserts the
    runtime lists match exactly

T02 Binding service + in-memory link repo + active-state machine
  - src/binder/repos/in-memory-links.ts: Map-backed EvidenceLinkRepository
  - src/binder/services/bindings.ts: link/unlink/list/update/setActive
    emitting §4 EvidenceLinkCreated / EvidenceLinkUpdated /
    EvidenceItemActivated
  - src/binder/state/active.ts: (target, evidence, annotation) reducer
    + ActiveStateProvider + useActiveState hook
  - extended engine/events/types.ts with EvidenceLinkCreated,
    EvidenceLinkUpdated, FormFieldActivated payloads

T03 Rect registry (SharedContracts §7 — contract FROZEN)
  - src/binder/visual-guide/rect-registry.ts: register/getRect/subscribe
    + invalidate + getVersion for useSyncExternalStore
  - events.ts: scroll/resize/focus pumps via window + ResizeObserver +
    IntersectionObserver, rAF-throttled
  - react-hooks.ts: RectRegistryProvider, useRegisterRect(kind,id,ref),
    useRectRegistryVersion

T04 Form schema + renderer
  - src/app/forms/demo-schema.ts: text/textarea/date minimal schema
  - src/binder/FormRenderer.tsx: renders schema, each field registers
    as rect kind="field"; active field gets aria-current="true"
  - placed in binder/ (not work/) because work cannot import binder per
    DependencyMap.md §2 and the renderer needs the rect-registry hook;
    workplan T04 was amended in-place to document this

T05 Side-by-side Forms layout + click-to-link
  - src/app/forms/FormsApp.tsx + src/app/App.tsx top-bar router with
    hash route #/forms/demo
  - BinderProvider mounted at app root so links survive tab switching
  - stage-evidence-then-click-field linking interaction with banner
    + per-field link-count chip

T06 Active-evidence cycling
  - src/app/forms/ActiveEvidenceChips.tsx: chips per active target,
    Tab cycles natively, first chip auto-activates on field focus,
    each chip registers as rect kind="evidence-card"
  - ScrollBridge in FormsApp wires activeAnnotationId to viewer scroll
  - EvidenceSidebar + EvidenceStrip highlight the active item via the
    new useLastActivatedEvidence hook in work/EngineContext

T07 SVG visual-guide overlay
  - src/binder/visual-guide/Overlay.tsx: single fixed-positioned SVG,
    draws field→card and card→highlight bezier curves for the active
    triple, rAF-throttled via the registry
  - src/anchor exposes getHighlightClientRects(annotationId); the
    spike viewer wraps highlights in [data-highlight-id] so the helper
    can locate them
  - src/app/forms/HighlightRectBridge.tsx: registers the active
    annotation's rect via that helper

T08 End-to-end test (PRD scenario steps 5-9)
  - tests/integration/forms-overlay-e2e.dom.test.tsx: full path from
    Review-mode capture through Forms-mode link to active triple +
    aria-current assertions + 2 SVG paths in the overlay
  - additional integration coverage: forms-link-flow + forms-active-cycling

/**
* CE-WP-0003-T06 integration — focusing a field auto-activates its first
* linked evidence, the chip is marked aria-current, and the ScrollBridge
* fires scrollTo on the viewer with the right annotation.
*
* Flow:
* 1. Review mode: open fixture, inject a selection capture, save the
* evidence item (T09 pattern).
* 2. Switch to Forms mode.
* 3. Stage the saved evidence in the strip.
* 4. Click a field → BindingService creates a link.
* 5. Click the field again → ActiveStateProvider focuses target →
* chip list re-derives → auto-activates first chip → ScrollBridge
* calls scrollTo → mock viewer sees `scrollToAnnotationId`.

/**
* CE-WP-0003-T05 integration — the side-by-side Forms layout +
* click-evidence-then-click-field linking interaction.
*
* Mirrors `app-prd-scenario.dom.test.tsx` (T09 of CE-WP-0002):
* - mocks `@anchor/index` to swap PdfSpikeViewer for an inert div
* - mocks `@source/index.ingestPdf` to skip PDF.js
*
* The flow:
* 1. Render <App />, switch to Forms mode via the top-bar button.
* 2. Open the fixture (CollectionList click).
* 3. Seed an EvidenceItem directly via the engine (creating one through
* the UI requires Review mode and is exercised by T09).
* 4. Click the evidence card in the strip → staged for linking.
* 5. Click a form field → BindingService.linkEvidenceToTarget called.
* 6. The field's link-count chip shows "1 evidence".
