fix(#2893): surface non-canonical plan filenames instead of silently returning zero plans (#2896)

* fix(#2893): surface non-canonical plan filenames instead of silently returning zero plans

Reporter saw `plan_count: 0` from `/gsd:execute-phase` even though five
plan files existed on disk. Investigation showed the planner had written
files like `01-PLAN-01-foundation.md`, while `phase-plan-index`'s strict
filter (`f.endsWith('-PLAN.md') || f === 'PLAN.md'`) rejected them
silently — collapsing two distinct states into the same `plans: []`
return:

  - directory truly has no plans (legit empty)
  - directory has plans but the filter rejected them (user/agent error)

The canonical contract is documented in three places:
  - `agents/gsd-planner.md` write_phase_prompt step (lines 1063-1080)
  - `commands/gsd/plan-phase.md`
  - `references/universal-anti-patterns.md` (rule 26)

It mandates `{padded_phase}-{NN}-PLAN.md` and explicitly forbids
`PLAN-NN.md` / `01-PLAN-01.md` / `plan-NN.md` etc. The strict filter is
correct per that contract. The bug is that the executor never tells the
user when the contract was violated — they just see `plan_count: 0`
with no signal.

Fix: add a diagnostic helper `describeNonCanonicalPlans()` that scans
the phase directory for files matching `*PLAN*.md` (the diagnostic net)
that the canonical filter rejected, excluding legit derivatives like
`*-PLAN-OUTLINE.md` and `*-PLAN.pre-bounce.md`. When offenders exist,
return a `warning` field naming each one and citing the canonical
pattern so the user knows what to rename to.

Wired into the three filter sites:
  - `phase-plan-index` (the executor's main entry point)
  - `phases list --type plans`
  - `find-phase`

The strict filter itself is unchanged — existing canonical plans behave
identically. This is purely a diagnostic that converts silent-empty
into loud-with-actionable-error.

Tests:
  - `phase-plan-index returns warning for reporter's exact filename
    pattern (`01-PLAN-01-foundation.md`)`
  - `truly empty dir does not emit a warning`
  - `canonical plans + outline + pre-bounce files do not emit a warning`

Closes #2893

* test(#2893): add parity tests for find-phase and phases list --type plans warnings

CodeRabbit's only finding on the prior commit: I wired the warning into
three filter sites (`phase-plan-index`, `find-phase`,
`phases list --type plans`) but only `phase-plan-index` had test
coverage for the warning shape. The other two paths could silently
diverge during future refactors — exactly the silent-drift class of bug
this fix exists to prevent.

Add four parity tests mirroring the existing two:

  - find-phase: non-canonical filenames produce a warning naming each
    offender + citing the canonical pattern.
  - find-phase: canonical plan + derivative files (PLAN-OUTLINE,
    pre-bounce) produce no warning.
  - phases list --type plans: same non-canonical case, but assert the
    warning is prefixed with `${dir}: ` (this path aggregates across
    phase directories so each offender is tagged with its dir).
  - phases list --type plans: canonical case, no warning.

`node --test tests/phase.test.cjs`: 98/98 pass (was 94, +4 new).
