fix(3600): count project-code-prefixed phase dirs in milestone filter

`init.new-milestone` reported `phase_dir_count: 0` for projects whose
phase directories carry a project_code prefix (`.planning/phases/CK-01-name`)
when the ROADMAP used numeric `### Phase N:` headings. Verified via a
temp-project repro that mirrors the reporter's setup.

Root cause: `getMilestonePhaseFilter` builds an `isDirInMilestone(dirName)`
predicate that tries two paths:

  1) Numeric — requires the dir name to START with a digit. `CK-01-name`
     starts with `C`, so this skips.
  2) Custom-ID — captures the leading kebab token (`CK-01-name` as a
     whole) and compares it to the normalised milestone phase IDs
     (`{"1"}`). No match.

There was no path that stripped the project_code prefix before retrying
the numeric match. Added a third path that strips the same shape
`normalizePhaseName` already recognises (`^[A-Z]{1,6}-(?=\d)`) and retries
the numeric match. This runs AFTER the custom-ID path so a ROADMAP that
uses `### Phase PROJ-42:` continues to win via the custom-ID match for
a `PROJ-42` directory; the new branch only fires when the milestone is
keyed on the bare numeric form.

The fix lands in both:

  - get-shit-done/bin/lib/core.cjs:isDirInMilestone (active CJS runtime)
  - sdk/src/query/state.ts:isDirInMilestone (SDK twin)

`getMilestonePhaseFilter` is shared by multiple callers — init.new-milestone,
phase complete, verify-work, validate-health — so the fix benefits every
caller that walks `.planning/phases/` against a numeric ROADMAP.

Regression test
(tests/bug-3600-milestone-phase-filter-project-code-prefix.test.cjs):

  1. Reporter's case: CK-01-name + CK-02-build dirs against Phase 1 / 2
     headings → phase_dir_count === 2.
  2. Existing contract: 01-first dir against Phase 1 heading still counts.
  3. Custom-ID contract: PROJ-42 dir against `### Phase PROJ-42:` still
     counts via the existing custom-ID match (no regression).
  4. Counter-test: CK-99-backlog and CK-100-future dirs MUST NOT count
     against a milestone with only Phase 1 — the strip-and-retry must
     still respect the milestone's actual phase set.

All assertions go through `init new-milestone --json` (typed payload —
`phase_dir_count`). No raw text matching.

**`init.new-milestone` now counts project-code-prefixed phase directories** — `getMilestonePhaseFilter` previously skipped `.planning/phases/CK-01-name` against a numeric ROADMAP heading like `### Phase 1:`: the numeric matcher required the directory name to start with a digit and the custom-ID matcher compared the full prefixed name against the bare milestone token. Added a strip-and-retry path that strips the same `^[A-Z]{1,6}-(?=\d)` prefix `normalizePhaseName` already recognises and retries the numeric match. The fix lands in both the CJS runtime (`get-shit-done/bin/lib/core.cjs:isDirInMilestone`) and the SDK twin (`sdk/src/query/state.ts:isDirInMilestone`), and is shared by every caller of `getMilestonePhaseFilter` — including `init.new-milestone`, `phase complete`, `verify-work`, and `validate-health`.
