Tom Boucher 809c2bee39 fix(sdk): expand short-form depends_on for decimal-phase plans (#3488)
The DAG resolver in phase-plan-index only matched full-stem
('03-01-auth-hardening') and canonical-prefix ('03-01') forms when
resolving `depends_on` references, so plans in decimal phases
(e.g. `99.9-test`, `02.2-cross-repo`) declaring short-form
`depends_on: [01]` had their edges silently dropped. Dependents
collapsed into wave 1 and the SDK emitted a misleading
"declared wave: N but depends_on DAG places it in wave 1" warning
that pointed at the wave declaration rather than the broken reference.

Add a tertiary short-form index keyed on the trailing `-NN` of each
plan's canonical ID — derived per plan via `lastIndexOf('-')` so it
handles integer, letter-suffixed, and decimal phase IDs uniformly.
Emit a dedicated `Plan X: unresolved depends_on reference 'NN' — no
matching plan in phase` warning whenever a dep fails all three lookup
forms, so a dropped edge can no longer hide behind the wave-mismatch
warning.

Regression coverage added in `sdk/src/query/phase.test.ts` for the
decimal-phase short-form case, the integer-phase short-form case, and
the unresolved-reference warning.

Fixed 3488

phase-plan-index resolves short-form depends_on: [NN] for decimal-phase plans — the DAG resolver only matched full-stem (03-01-auth-hardening) and canonical-prefix (03-01) forms, so plans in decimal phases (e.g. 99.9-test, 02.2-cross-repo) declaring depends_on: [01] had their edges silently dropped. Dependents collapsed into wave 1 and the SDK emitted a misleading declared wave: N but depends_on DAG places it in wave 1 warning that pointed at the wave declaration rather than the broken reference. A tertiary short-form index now maps the trailing -NN of every plan ID to its full ID for same-phase short-form lookups, and unresolved depends_on references surface a dedicated Plan X: unresolved depends_on reference 'NN' — no matching plan in phase warning so the dropped edge can no longer hide behind the wave-mismatch warning.
