Nothing waits behind a label no one asked for: the Later gate holds silently #7797

Live triage no longer holds an issue behind the Later gate for lacking a pillar, and the automatic "no pillar named…" comment is gone. tsc --noEmit is clean and test/livetriage.test.ts passes (34 tests); I didn't run the rest of the suite.

What changed

• In src/crew/livetriage.ts, an issue that names no pillar is now left exactly as filed: no gate link, no Later label, no comment. Issues whose title or body names a pillar are still filed under it, with the same note.
• Such issues no longer count as missed in the tick line. missed now only means the per-tick cap of 25 was hit.
• A repository with a gate but no pillars now has nothing to file under, so triage does nothing there.
• docs/CREW.md describes the new rule.

Tests

• Updated test/livetriage.test.ts: the old "goes to Later with a comment" cases now assert no hold, no label and no comment.
• The "unlinks the gate" case now unfiles a pillar-filed issue instead.
• The cap test uses issues that name a pillar.

Not done

• Issues already gated by the old rule (#7636, #7637 and any others) are not released automatically. Someone has to unlink them from the gate, or I can add a one-off release if you want it.
• I did not add the "page says what holds this issue, with a release button" item. Nothing in triage holds an issue for lacking a pillar any more, so it only applies to holds that are deliberate, such as FLOW ONLY or a person's own Later. I didn't check whether those pages already show it.

Live triage no longer holds an issue behind the Later gate for lacking a pillar. An issue that names no pillar gets no gate, no label and no comment, and missed (the triageMiss=N count) now counts only issues the cap left over. This round fixes the five leftovers from the old rule.

• docs/CREW.md: triageMiss=N is now described as issues naming a pillar that the 25-per-tick cap left for the next tick.
• file doc comment in src/crew/livetriage.ts: it now says the same: how many were filed, and how many that name a pillar the cap left for next tick.
• The ! assertion: file now pairs each issue with its pillar up front, skipping issues that name none. The loop runs over those pairs, so the pillar can't be undefined.
• Test world: nogate is now unnamed.
• Issues already held (#7636, #7637 and others): I did not release them here. It is a data change on the live forge, so I opened #7801 to unlink them and confirm triage doesn't re-hold them.

bun x tsc --noEmit is clean and test/livetriage.test.ts passes (34 tests). I ran no other test files.
