fix(3785): case-insensitive depends_on resolution in phase resolver (#88)

* fix(3785): case-insensitive depends_on resolution in phase resolver

planMap, canonicalToId, and shortFormToId in phasePlanIndex used strict
Map.has() with no case normalization. A depends_on ref in mixed/lowercase
against an uppercase-suffix plan ID (e.g. '20-01-auth' → '20-01-Auth')
dropped the DAG edge, assigning the dependent plan to wave 1 instead of
wave 2. Fix: normalize all keys and lookup values to lowercase so the
three-tier resolution is case-insensitive. Adds regression test (#3785).

* fix(3785): detect case-fold collisions; apply lowercase-both to CJS path

- Add collision guard in both sdk/src/query/phase.ts (phasePlanIndex)
  and get-shit-done/bin/lib/phase.cjs (cmdPhasePlanIndex): when two plan
  IDs in the same phase are identical after toLowerCase(), throw/error
  immediately with a clear message naming both files instead of silently
  overwriting one in planMap and misrouting depends_on edges.
- Apply the same lowercase-both normalization (#3785) to cmdPhasePlanIndex
  in phase.cjs, which was missing from the original PR — planMap and
  canonicalToId keys are now lowercased on write; dep strings are
  lowercased before lookup.
- Add regression tests to tests/phase.test.cjs: case-insensitive
  resolution test (runs on all platforms) and collision-detection test
  (skipped on macOS/Windows where FS is case-insensitive).
- Update changeset to describe both the SDK and CJS fixes.

Identified via Codex adversarial review of PR #3798.

* fix(3785): address review — KNOWN GAP comment for CJS shortFormToId, canonical-casing tests, depends_on output normalization

- F1: Reword changeset for accuracy (plannerID drift trigger; two-tier CJS gap honest).
  Add KNOWN GAP comment in phase.cjs before Kahn's loop noting CJS lacks shortFormToId
  (tracked as follow-up parity gap, out of scope for #3785).
- F2: Add strict planA.id === '20-01-Auth' assertions in both SDK (vitest) and CJS (node --test)
  tests — a future regression that silently lowercases stored IDs would now fail the test.
- F3: Normalize depends_on output to canonical plan IDs in both SDK phase.ts and CJS phase.cjs.
  User-typed '20-01-auth' in depends_on resolves to '20-01-Auth' in output via planMap lookup.
  Add planB.depends_on === ['20-01-Auth'] assertions in both test suites.
- F5: Add seenLower guard-scope comment (full-ID collisions only; shared-prefix collisions
  handled by first-write-wins from sorted planFiles).
- F6: Add ASCII-safe toLowerCase comment at first call site in both SDK and CJS.
- F7: Add intentional-separation comment on seenLower vs planMap in both SDK and CJS.

* test(3785): cover case-insensitive depends_on resolution branches

Add 4 focused test cases exercising branches introduced by #3785:
- All-uppercase depends_on ref resolving to lowercase plan ID via planMap
- External cross-phase dep preserved as-is in Pass 3 output (planMap miss)
- Mixed-case short canonical prefix resolving via canonicalToId
- Plans with undefined/empty depends_on emit empty array correctly

**`phasePlanIndex` and `phase-plan-index` no longer drop `depends_on` edges when plan IDs and dep references differ in case** — fixes wrong wave assignment for plans with `depends_on` references that case-fold differently from canonical plan IDs (e.g. from gsd-planner output that occasionally lowercases IDs) now resolve correctly via case-insensitive lookups while preserving canonical on-disk casing in output. Lowercased identifier lookups now resolve case-mismatched `depends_on` references in the two resolution tiers present in both SDK and CJS (`planMap` + `canonicalToId`). The SDK has an additional `shortFormToId` short-form tier; CJS does not — this PR does not backfill that tier (tracked as a follow-up parity gap). An explicit collision error is thrown when two plan files in the same phase produce IDs that are identical after case-folding, preventing silent DAG rewiring.
