Talk's hourly check-in names the releases cut since the last one and the pillars that moved #11470

The hourly check-in now names the releases cut and the pillars that merged work since the last check-in. tsc is clean, bun scripts/gate.ts printed nothing, and test/talk-captain.test.ts passes (17 tests). I didn't run the keep_plan tool; it isn't available here.

What changed

• New module: src/crew/routine_facts_story.ts gathers the facts. It reads the releases from readChangelog and the pillar counts from mergedByPillar. It skips both quietly when the forge has no public source repo or no pillars.
• Facts: it extends Story, which adds releases and pillarsMoved. facts() is now async and takes the time of the last check-in. The first run has no last check-in, so it looks back one hour.
• compose: the wording is one clause, appended to the check-in's third line (the crew-holds line). It reads like released 0.7.9, 0.7.10; moved: Trust 2. The clause shows at most 3 versions and 3 pillars. When more than 3 versions were cut it reads released 5 (to 5) (count, then newest version). It never sets needs, and the cap stays at three lines.
• Tests: they cover the clause shown, absent when nothing moved, at most three lines with needs false, and the release filtering by time.
• Docs: docs/features/talk-captain.md now says what the check-in reports, and "Not here yet" shrinks to child forges stuck.

Left out

• Child forges stuck is still missing.
• #checkin2: it edits the same Facts, so whichever lands second needs a small rebase.

Try it: open Settings › Captain and press Post now on the check-in, or run bun test test/talk-captain.test.ts.

The gathering half now has tests against a real forge, and I pushed them to the same branch. tsc is clean, bun scripts/gate.ts printed nothing, and the 20 tests in test/talk-checkin-story.test.ts and test/talk-captain.test.ts pass. I did not run the new tests against a deliberately broken storyFacts or a wrong sinceMs to confirm they fail.

Tests (new test/talk-checkin-story.test.ts): it seeds a public repo with two pillar issues, two merged pulls and two release commits.

• storyFacts counts only the pull merged inside the window (pillarsMoved is P0 Trust 1). The pull merged 5 hours earlier is left out, and a wider window counts both.
• storyFacts names the releases cut after the window opened, oldest first, and none for a future window.
• runRoutine is run twice. The first post says released 0.1.1, 0.1.2; moved: P0 Trust 1 and stores lastAt. The second post has no releases or pillars.

Review points

1. Date edge: commitLog reads %aI, which is strict ISO 8601 with a time and zone offset, so Date.parse is exact at the window edge. I left releasesSince as it is.
2. Type-guard cast: I replaced the .filter guard in storyFacts with a plain loop.
3. Doc line: docs/features/talk-captain.md now says the window is lastAt and that the git changelog is cached by head oid, so a check-in between releases costs only a rev-parse.
