Tom Boucher 1e091d2bcb refactor(shell-projection): remove deprecated wrappers + finalize ADRs (Phase 4, #3468) (#3484)
* refactor(shell-projection): remove deprecated wrappers + finalize ADRs (Phase 4, #3468)

Final phase of the shell-command-projection expansion. Removes the legacy
core.cjs wrappers (`atomicWriteFileSync`, `safeReadFile`, `normalizeMd`)
now that every call site lives behind the seam, plus three Phase-3
stragglers (`graphify.cjs`, `template.cjs`, dead import in
`profile-pipeline.cjs`).

Documentation:
- ADR-0009: addendum noting Phase 1–4 scope expansion (subprocess +
  file I/O ownership), supersession of "does not execute" constraint,
  and resolution of open Q4.
- ADR-0010: status changed to Superseded by ADR-0009 with explanation.
- CONTEXT.md "Shell Command Projection Module" entry already current
  from Phase 1 — no edit needed.

Tests:
- `tests/atomic-write.test.cjs` deleted — wrapper it tested is gone;
  `atomic-write-coverage.test.cjs` (Phase 3) covers platformWriteSync.
- `tests/core.test.cjs::safeReadFile` + `::normalizeMd` describes
  deleted — wrappers are gone.
- `tests/concurrency-safety.test.cjs` normalizeMd suite (behavioral /
  perf / snapshot) repointed via 2-line shim at the seam's
  `normalizeContent` — full regression coverage preserved.

Test result: 9059/9041/18 — exact pre-Phase-4 baseline. All 18
failures are pre-existing path-with-spaces local-env issues.

Closes #3468

* refactor(shell-projection): migrate remaining raw fs.writeFileSync sites (Phase 4, #3468)

Sweeps the 7 raw fs.writeFileSync call sites that bypassed the seam through Phase 3,
folding them into platformWriteSync. Net -14 lines: deletes the local writeFileAtomicSync
helper in installer-migrations.cjs and collapses surface.cjs's manual tmp+rename into a
single seam call.

Sites migrated:
- drift.cjs (1) — frontmatter write
- learnings.cjs (1) — learning record JSON write
- install-profiles.cjs (1) — profile marker write (collapsed redundant mkdir)
- gsd2-import.cjs (1) — imported file write (collapsed redundant mkdir)
- surface.cjs (1) — surface state write (replaced manual tmp+rename block)
- installer-migrations.cjs (3) — journal init/finalize + rewrite-json action;
  deleted private writeFileAtomicSync helper and its three call sites

Two sites intentionally retained outside the seam:
- planning-workspace.cjs:241 — workspace lock (wx-flag atomic-create; previously excluded by Phase 3)
- installer-migrations.cjs:220 — install migration lock (fd write into wx-opened handle)
- writeInstallState (installer-migrations.cjs) — strict atomic contract for install state;
  the seam's fallback-to-direct-write on rename failure would silently violate the
  invariant that install state must never be left half-written. Inline tmp+rename with
  rethrow keeps the original guarantee.

Tests: 9059 / 9041 / 18 — exactly the pre-Phase-4 baseline; 18 failures are the
pre-existing path-with-spaces local-env issues, identical files as before.

* fix(installer-migrations): use strict atomic write for rollback install-state restore

The rollback path was restoring INSTALL_STATE via platformWriteSync, which falls
back to a direct write on rename failure and would silently violate the
half-written invariant that the install-state contract guarantees elsewhere.

Extracts the strict tmp+rename logic from writeInstallState into a shared
atomicWriteInstallState(configDir, content) helper and routes both
writeInstallState and rollbackAppliedMigrationResult through it. Preserves the
existing null-handling (rmSync when previousInstallStateBytes === null) and
existing failure-collection (failures.push on caught errors).

Byte-faithful restore: previousInstallStateBytes is written as-is (no JSON
parse round-trip), preserving the exact prior file contents on restore.
