Tom Boucher e437ded6fc docs(3524): CJS↔SDK hard-seam ADR + phased PRD (#3529)
* docs(3524): propose CJS↔SDK hard-seam ADR + phased PRD

Adds docs/adr/3524-cjs-sdk-hard-seam.md (Proposed) and
docs/prd/3524-cjs-sdk-hard-seam.md (Reference) tracking #3524.
Updates the ADR and PRD index READMEs.

The ADR defines one canonical owner per responsibility across the
CJS (bin/lib/*.cjs) and SDK (sdk/src/**/*.ts) sides, eliminating the
recurring drift bug class (#1535, #1542, #2047, #2638, #2653, #2687,
#2798, #3055, #3523). Three layers: shared data (sdk/shared/*.json),
shared core logic (sdk/src/core/ → dual CJS+ESM build), thin adapters.
Enforcement is layered: build-time grep, type-level contract test,
mutation parity test, CODEOWNERS gate, in-file banner.

The PRD phases the migration in five independently shippable steps —
shared data first (closes constant drift), then config consolidation
(closes #3523 class), then project-root + path projection, then state
and verify handlers, then enforcement hardening + retrospective.

* docs(3524): revise seam ADR + PRD after architecture review

Architecture-review pass (via /improve-codebase-architecture) found
seven deepening opportunities; this commit applies all of them.

1. Re-anchor on the existing generator precedent. The repo already
   has sdk/scripts/gen-command-aliases.ts emitting both
   .generated.ts and .generated.cjs from one TS source, with
   sdk/scripts/check-command-aliases-fresh.mjs as the CI freshness
   gate. The ADR's invented dual CJS+ESM bundler pipeline is
   dropped. Each Shared Module gets one generator script and one
   freshness check, modeled on that precedent.

2. Drop the generic sdk/src/core/ container. The canonical-owner
   table is now indexed by Module, using the CONTEXT.md domain
   vocabulary (STATE.md Document Module, Configuration Module,
   etc.) rather than file-path-based pseudo-modules.

3. Split the coarse "State management" row into three: the pure
   STATE.md Document Module (already a character-identical
   hand-synced pair — perfect Phase 1 target), the Planning
   Workspace Module (defer to ADR-0004), and per-side state I/O
   Adapters (legitimately differ sync vs async).

4. Defer to existing ADRs. Planning Path Projection (ADR-0006),
   Model Catalog (ADR-0003), Planning Workspace (ADR-0004),
   Dispatch Policy (ADR-0001), Shell Command Projection (ADR-0009
   post-Phase 3-4 expansion which absorbed superseded ADR-0010).
   The stale ADR-0010 reference is fixed.

5. Define a Configuration Module entry in CONTEXT.md as a Phase 2
   deliverable, with explicit Interface contract for loadConfig,
   normalizeLegacyKeys, mergeDefaults, migrateOnDisk.

6. Split the Workstream Inventory Module into a pure Builder
   (generated, shared) and per-side Reader Adapters (hand-authored,
   sync vs async). Same pattern generalizes to other paired Modules.

7. Match enforcement to existing scripts. Per-Module freshness
   checks (precedent: check-command-aliases-fresh.mjs), per-Module
   drift lints (precedent: lint-shell-command-projection-drift.cjs),
   and one hand-sync pair lint that blocks the #3523 anti-pattern
   at PR time.

PRD phases reordered: STATE.md Document Module ships first as a
proof of pattern (two identical files become one source plus one
generated artifact). Configuration Module ships second, closing
the #3523 class. Workstream Inventory Builder split third.
Project-Root Resolution fourth. Enforcement and retrospective
fifth.

* docs(3524): expand scope — CJS router delegates to SDK runtime bridge

User flagged that the original "Out of scope" list was my unilateral
scoping call, not theirs. After review, the CJS router consolidation
(formerly out-of-scope item #1) is brought into scope.

ADR additions:
- CJS Command Router Adapter Module row added to canonical-owner
  table. Existing Module (per CONTEXT.md) is amended so the
  per-family `handlers` map delegates to `QueryRuntimeBridge.execute()`
  in-process. Per-side CJS handler files for canonical families
  (state.cjs, verify.cjs, init.cjs, phase.cjs, etc.) shrink to
  delegates or are deleted.
- Per-side I/O Adapter consequence updated to clarify the bridge
  preserves the in-process model. No subprocess hop is added.
- "Out of scope" stripped of router item; CJS-only seam migration
  and verify-Module-first work remain out of scope.

PRD additions:
- New Phase 5: CJS Command Router Adapter delegates to SDK runtime
  bridge, family-by-family, with golden parity matrix per family
  gating each PR.
- Old Phase 5 (enforcement) renumbered to Phase 6, expanded to cover
  Phase 5's parity matrix and runtime-bridge CODEOWNERS.
- Open question #4 added for the synchronous-bridging mechanism
  (`deasync` vs `Atomics.wait` vs sync-handler refactor) — resolved
  in the Phase 5 spike before any family migration begins.
- Open question #5 added for family migration order (recommended:
  smallest read-only family first).
- Risks table expanded with three Phase 5 rows: bridging-mechanism
  uncertainty, observable-output regression, startup-time impact.
- Done-when updated for six phases and five enforcement layers.

Non-goals updated: CJS-only Module migration and verify-Module
deepening remain out of scope. CJS CLI removal explicitly stays
off the table — the external `gsd-tools` contract is preserved.
