fix(3): milestone.complete header dup, bullet leakage, one-liner noise (#146)

* test(3): add failing tests for milestone.complete header-dup, bullet-leakage, one-liner-noise

Three RED tests for confirmed-bug #3 in sdk/src/query/phase-lifecycle.test.ts:

Defect 1 (header-dup): milestoneComplete produces "## v1.0 v1.0 (Shipped: ...)"
when no --name is given because `milestoneName = nameOpt || version` is always
truthy, so the template `## ${version} ${milestoneName}` duplicates the version.
Two sub-cases: no --name, and --name "Foundation Release".

Defect 2 (bullet-leakage): getMilestonePhaseFilter falls back to passAll
(milestonePhaseNums.size === 0) when the milestone section declares phases via
GFM task-list bullets only (https://github.github.com/gfm/#task-list-items-extension-)
with no ### Phase N: headings, admitting unrelated phase 99.

Defect 3 (one-liner-noise): extractOneLinerFromBody matches the first bold in the
entire document body after the heading, regardless of section boundaries.
Per GFM § ATX headings (https://github.github.com/gfm/#atx-headings), the scope
must be bounded to "first heading until next heading of ANY level".

CJS bundle `bin/lib/*.cjs` intentionally NOT updated; bundle sync covered by #4
(first generator-introducing PR) and #26.

* fix(3-1): preserve version in milestone header, append name only when provided

Bug: `milestoneName = nameOpt || version` was always truthy (falling back to
version), so the template `## ${version} ${milestoneName}` rendered as
`## v1.0 v1.0 (Shipped: ...)` when no --name was given.

Fix: separate `milestoneName = nameOpt ?? undefined` from `version`, then
build the title with `milestoneName ? \`${version} ${milestoneName}\` : version`.

Canonical template (GFM § ATX headings: https://github.github.com/gfm/#atx-headings):
  No --name:          `## v1.0 (Shipped: 2026-05-23)`
  With --name "Foo":  `## v1.0 Foo (Shipped: 2026-05-23)`

Historical evidence: `## v1.8.0 Quick Mode (Shipped: 2026-01-19)`

Also applies the same fix to the Requirements Archive header.

* fix(3-2): recognize checkbox-bullet phase declarations in milestone phase filter

Bug: getMilestonePhaseFilter in sdk/src/query/state.ts used the regex
`/#{2,4}\s*Phase\s+([\w][\w.-]*)\s*:/gi` which only matched heading-style
phase declarations (### Phase N: title). When a ROADMAP declares phases via
GFM task-list bullets only:

  - [ ] **Phase 1: Foundation**
  - [ ] **Phase 2: API**

the Set remained empty → passAll fired → all phase directories (including
unrelated 99-*) were admitted into the milestone accomplishments.

Fix: extend the regex to also match bullet-style declarations:
  /(?:#{2,4}\s*|-\s*(?:\[[x ]\]\s*)?\*{0,2}\s*)Phase\s+([\w][\w.-]*)\s*:/gi

* fix(3-3): bound extractOneLinerFromBody to first heading until next heading of any level

Bug: extractOneLinerFromBody in sdk/src/query/phase-lifecycle-policy.ts
used the regex /^#[^\n]*\n+\*\*([^*]+)\*\*/m which matched the first bold
in the entire document body after any heading. This leaked bold text from
later sub-sections (e.g. "### Deviation 1 -- bar") into the one-liner.

Fix: bound the search scope to the first section only.
Implementation follows D3 spec:
  1. Find the first heading of any level (GFM ATX headings:
     https://github.github.com/gfm/#atx-headings).
  2. Extract content from after that heading to the next heading of ANY level
     (not "same or higher") so ### Deviation terminates scope even when title
     is H1.
  3. Match the first **bold** within that bounded scope only.

Note: TypeScript 5.x rejects backtick-containing regex patterns in JSDoc
comments (TS1443: template literal parse error); comments use plain text instead.

* fix(3-3): apply bounded one-liner extraction to summary.ts duplicate

Sibling copy of extractOneLinerFromBody in sdk/src/query/summary.ts had
the same pre-fix logic flagged in commit d1eab690. Same bug, same fix —
"Fix Everything You Find" applies. DRY-extracting to a shared module is
left as a follow-up refactor; out of scope for this bug fix.
