feat(hooks): add gsd-read-injection-scanner PostToolUse hook (#2201) (#2328)

* feat: add /gsd-spec-phase — Socratic spec refinement with ambiguity scoring (#2213)

Introduces `/gsd-spec-phase <phase>` as an optional pre-step before discuss-phase.
Clarifies WHAT a phase delivers (requirements, boundaries, acceptance criteria) with
quantitative ambiguity scoring before discuss-phase handles HOW to implement.

- `commands/gsd/spec-phase.md` — slash command routing to workflow
- `get-shit-done/workflows/spec-phase.md` — full Socratic interview loop (up to 6
  rounds, 5 rotating perspectives: Researcher, Simplifier, Boundary Keeper, Failure
  Analyst, Seed Closer) with weighted 4-dimension ambiguity gate (≤ 0.20 to write SPEC.md)
- `get-shit-done/templates/spec.md` — SPEC.md template with falsifiable requirements
  (Current/Target/Acceptance per requirement), Boundaries, Acceptance Criteria,
  Ambiguity Report, and Interview Log; includes two full worked examples
- `get-shit-done/workflows/discuss-phase.md` — new `check_spec` step detects
  `{padded_phase}-SPEC.md` at startup; displays "Found SPEC.md — N requirements
  locked. Focusing on implementation decisions."; `analyze_phase` respects `spec_loaded`
  flag to skip "what/why" gray areas; `write_context` emits `<spec_lock>` section
  with boundary summary and canonical ref to SPEC.md
- `docs/ARCHITECTURE.md` — update command/workflow counts (74→75, 71→72)

Closes #2213

* feat(hooks): add gsd-read-injection-scanner PostToolUse hook (#2201)

Adds a new PostToolUse hook that scans content returned by the Read tool
for prompt injection patterns, including four summarisation-specific patterns
(retention-directive, permanence-claim, etc.) that survive context compression.

Defense-in-depth for long GSD sessions where the context summariser cannot
distinguish user instructions from content read from external files.

- Advisory-only (warns without blocking), consistent with gsd-prompt-guard.js
- LOW severity for 1-2 patterns, HIGH for 3+
- Inlined pattern library (hook independence)
- Exclusion list: .planning/, REVIEW.md, CHECKPOINT, security docs, hook sources
- Wired in install.js as PostToolUse matcher: Read, timeout: 5s
- Added to MANAGED_HOOKS for staleness detection
- 19 tests covering all 13 acceptance criteria (SCAN-01–07, EXCL-01–06, EDGE-01–06)

Closes #2201

* fix(ci): add read-injection-scanner files to prompt-injection-scan allowlist

Test payloads in tests/read-injection-scanner.test.cjs and inlined patterns
in hooks/gsd-read-injection-scanner.js legitimately contain injection strings.
Add both to the CI script allowlist to prevent false-positive failures.

* fix(test): assert exitCode, stdout, and signal explicitly in EDGE-05

Addresses CodeRabbit feedback: the success path discarded the return
value so a malformed-JSON input that produced stdout would still pass.
Now captures and asserts all three observable properties.
