fix(#1639): parseDecisions handles the titled-colon bullet form (#1665)

* fix(#1639): parseDecisions handles titled-colon bullet form

bulletColonRe anchors on ':**' (colon immediately before close-bold) and bulletEmDashRe
requires an em-dash, so the titled-colon form '- **D-NN: Title.** body' (title between the
colon and the closing **) matched neither and was dropped by the parse-miss guard. When all
decisions used the titled convention, parseDecisions returned 0 and check.decision-coverage-
plan passed vacuously — the same false-coverage failure mode as #1343/#1364/#1365. Add a
third per-form regex bulletTitledColonRe, checked LAST (strict superset of bulletColonRe,
so it only catches bullets the other two miss — minimal blast radius); id + [tags]
trackability honored. Regression folded into decisions.test.cjs: titled-colon parses,
coexists with colon/em-dash, tags, all-titled-13 no longer vacuously 0.

* fix(#1639): tighten titled-colon title to [^:*]* so malformed pre-colon-run bullets still reject

The first cut's title run [^*]* was too permissive: it matched a genuinely-malformed
bullet with a colon in the pre-separator freeform run (e.g. 'D-07 ratio 3:1:**') by
treating the 3:1 colon as the separator, regressing the #1343 parse-miss guard tests.
Tighten the title to [^:*]* (no colon, no star) so the separator colon remains the only
colon permitted before ** — matching bulletColonRe's existing [^:*]* discipline. Valid
titled forms (colon-free titles) still parse; the malformed colon-in-freeform case still
falls through to the parse-miss guard.

* chore(#1639): backfill changeset pr ref to 1665

**`check.decision-coverage-plan` no longer false-passes when CONTEXT.md decisions use the titled-colon bullet form** — `parseDecisions` recognized the colon-immediate (`- **D-NN:** text`) and em-dash (`- **D-NN — title** body`) forms but dropped the titled-colon form (`- **D-NN: Title.** body`, where a title sits between the colon and the closing `**`) via the parse-miss guard. When all decisions used the titled convention, the parser returned 0 decisions and the coverage gate passed vacuously. A third per-form regex (checked last, a strict superset of the colon form) now parses the titled-colon form; id and `[tags]` trackability are honored.
