feat(#703): add --granularity override flag to /gsd:plan-phase (#750)

* feat(#703): add --granularity override flag to /gsd:plan-phase

Add a `--granularity <coarse|standard|fine>` flag to /gsd:plan-phase that
overrides the configured planning granularity for a single invocation.

The override is a new highest-priority tier above the existing precedence
chain (granularities[phaseType] -> granularity -> planning.granularity ->
'standard') in resolveGranularityInternal; when the flag is absent, resolution
is byte-for-byte unchanged. cmdInitPlanPhase now resolves with phaseType
'planning' so granularities.planning participates, and emits the resolved
value in the init JSON, which the plan-phase workflow forwards to the planner
prompt. Invalid values are rejected at the CLI boundary via a shared
assertValidGranularityOverride helper.

Closes #703

| `--skip-bounce` | Skip plan bounce even if enabled in config |
| `--mvp` | Vertical MVP mode — planner organizes tasks as feature slices (UI→API→DB) instead of horizontal layers. On Phase 1 of a new project with no prior phase summaries, also emits `SKELETON.md` (Walking Skeleton). Can be persisted on a phase via `**Mode:** mvp` in ROADMAP.md, which applies `--mvp` automatically without the flag. |
| `--tdd` | TDD mode — planner applies `type: tdd` to eligible behavior-adding tasks so each begins with a failing test. Composable with `--mvp`: `--mvp --tdd` produces vertical slices where every behavior-adding task starts red-green. |
| `--granularity <coarse\|standard\|fine>` | Override the planning granularity for this invocation, ignoring config. Valid values: `coarse`, `standard`, `fine`. Takes precedence over `granularities.planning`, top-level `granularity`, and `planning.granularity` config. |
**Prerequisites:** `.planning/ROADMAP.md` exists
**Produces:** `{phase}-RESEARCH.md`, `{phase}-{N}-PLAN.md`, `{phase}-VALIDATION.md`; `{phase}/SKELETON.md` when Walking Skeleton mode fires
