fix(dream): deterministic last-writer attribution for colliding slugs

collectChildPutPageSlugs paired each slug to a jobId first-seen over an
unordered result set. When two children collide on a final slug, the pages
row holds the LAST put_page write, so the provenance stamp
(transcript_id/transcript_source/date) could attribute an arbitrary other
transcript. ORDER BY id + last-writer-wins aligns the stamp with the
surviving content; pinned by a collision test.

+ *      layout; null for ad-hoc inputs that don't match.
+ *   2. Content-based date inference — the `| First message | <ISO> |` row in
+ *      the transcript's `## Metadata` table wins over the filename-regex
+ *      date (stable across mtime-restamping re-syncs); filename is the
+ *      fallback.
+ *
+ * Pure filesystem; no engine, no LLM.

- * propose_takes rescan-loop + dropped-claims regression tests (migration v125).

- * Two live-observed defects, both fixed by the v125 schema + phase change:
- *
- *   1. RESCAN LOOP — a page whose extraction yielded zero claims never
- *      entered the idempotency cache (only proposal rows were written), so
- *      every cycle re-spent the extractor call on the same unchanged page.
- *      Live impact: ~60 such pages × every cycle ≈ 1,400 wasted LLM calls
- *      (~$15) per day — ~90% of total autopilot spend. Fix: status='empty'
- *      sentinel row per zero-claim scan.
- *
- *   2. DROPPED CLAIMS — the 4-column unique index collapsed a same-page
- *      multi-claim run to its first claim (rows 2..N conflicted, ON CONFLICT
- *      DO NOTHING dropped them silently; verified live: exactly 1 row per
- *      (page, hash) over 3 days). Fix: idempotency index gains
- *      md5(claim_text).
- *
