Land the warming-files line from branch scout/6547-a-pure-read-names-the-files-that-gained, with its history tested and each line naming its repository #6598

This lands the warming-files line from #6560 (head 1ec4c880) on a new branch, merged cleanly with current main. It also covers the remaining review asks, with the sampling, history and tests described below. bun x tsc --noEmit, the touched tests and bun scripts/design-lint.ts pass; I did not run the full suite, which the forge's check does.

What changed

• Repository and heading: each warming line on the /boards flow panel already ended in owner/repo, under a small "Warming" heading, so I left that as #6560 built it.
• Fewer false alarms: hotTrend now leaves out files already at the hot-file limit, which the hot-file list names. HOT_PULLS moved into src/flow/hot_trend.ts so the read stays pure, and hot_files.ts re-exports it.
• Rises of one pull: I read "rises of a single pull" as any rise of 1, not only 0 → 1. A file must gain at least two open pulls to be named, so 1 → 2 is also left out. If you meant only 0 → 1, change to - from >= 2 in hotTrend.
• Injectable time: learnPullFiles takes an optional now, defaulting to Date.now(). hotFiles now reuses pullCounts instead of repeating the counting loop.
• Tests:

- New test/crew-hot-history.test.ts checks that two samples one minute apart keep one, that a two-hour-old sample is pruned, and that the 60-minute sample is the baseline among samples 40, 60 and 85 minutes old. - test/flow-hot-trend.test.ts has new cases for the limit and the single-pull rise. - test/crew-hot-files.test.ts drives learnPullFiles twice, an hour apart, and expects warming: src/warm.ts 1 → 3 pulls in alice/warm. Removing the sampleHeat call makes it fail; I ran that check, then restored the call.

Left out: samples stay in memory, so a restart starts the history over and nothing is said until a sample at least 30 minutes old exists.

To try: bun test test/crew-hot-history.test.ts test/flow-hot-trend.test.ts test/crew-hot-files.test.ts, then open /boards on a repository where open pulls are piling onto a file.
