v0.41.29.0 feat(conversation-parser): bold-name-no-time builtin + fix(orphans): source-scoped orphan_ratio (supersedes #1613) (#1620)

* feat(conversation-parser): add bold-name-no-time builtin (Circleback/Granola/Zoom, no timestamp)

The 14th built-in pattern parses `**Speaker:** text` transcripts with NO
per-line timestamp — the shape Circleback / Granola / Zoom emit. Every prior
builtin required a time anchor, so this shape matched nothing: a production
brain had 104 conversation pages + 3,423 eligible pages silently extracting
zero facts. Messages anchor at T00:00:00Z of the frontmatter date (no
fabricated wall-clock; line order preserves sequence), same convention as
irc-classic.

Hardening beyond the original community proposal:
- regex `/^\*\*(?!\[)(.+?):\*\*\s*(.*)$/`: the colon-inside-bold (NOT
  declaration order) is what prevents shadowing bold-paren-time; the `(?!\[)`
  lookahead rejects telegram-bracket `**[18:37] Name:**` so disabling
  telegram-bracket yields an honest no_match instead of speaker="[18:37] Name".
- new optional PatternEntry.score_full_body: `**Label:** text` is a common
  prose idiom, so a notes page with bold labels clustered in its first 10
  lines scored 0.3 on the head pass (NOT < SCORING_HEAD_TRIGGER_THRESHOLD, so
  the full-body fallback never fired) and cleared the 0.05 floor. parse.ts now
  recomputes the winner's score over the full body before the floor, so such a
  page drops to its true low density and stays no_match.
- scrubbed pre-existing real names from bold-paren-time test_positive samples
  (privacy rule).

Fixtures use placeholder names only. Pinned by new bold-name-no-time +
clustered-head no_match cases in parse.test.ts and the eval corpus.

* fix(orphans): scope orphan_ratio + find_orphans by source; fix total_linkable denominator

`gbrain doctor --source <id>` and `gbrain orphans --source <id>` now scope
the orphan scan to that source instead of reporting brain-wide. Three fixes:

- findOrphanPages(opts?: { sourceId?, sourceIds? }) on both engines scopes the
  CANDIDATE set (scalar `= $1` or federated `= ANY($1::text[])`). Inbound links
  from ANY source still count, so a page in source X linked FROM source Y is
  reachable and NOT an orphan of X (the deliberate, less-surprising definition).
- corrected the total_linkable denominator in findOrphans: it now enumerates
  all live pages (scoped) and subtracts every excluded-by-slug page, not just
  excluded orphans. The old `total - excludedOrphans` left excluded NON-orphan
  pages (templates/, scratch/) with inbound links in the denominator, inflating
  it and suppressing warnings. Changes orphan_ratio output for every brain, in
  the accurate direction.
- the find_orphans MCP op threads sourceScopeOpts(ctx), closing a cross-source
  read leak where a source-bound OAuth client saw brain-wide orphans (v0.34.1
  source-isolation class).

doctor uses an explicit `--source` flag parse (NOT resolveSourceWithTier, which
would scope bare invocations to a default), and under explicit --source reports
the ratio with a low-scale caveat below 100 entity pages instead of a vacuous
"ok". Thin-client doctor --source orphan_ratio deferred (TODOS.md).

Pinned by test/orphans-source-scope.test.ts (PGLite: scoping, cross-source
inbound, denominator, find_orphans op scope) + a Postgres↔PGLite parity case
in test/e2e/engine-parity.test.ts (scalar + federated binding).
