Add daily sweep to enforce issue lifecycle label timeouts

Introduce a simple, mechanical daily sweep that closes issues with
lifecycle labels past their timeout:

- needs-repro: 7 days
- needs-info: 7 days
- needs-votes: 30 days
- stale: 30 days

The sweep checks when the label was last applied via the events API,
and closes the issue if the timeout has elapsed. No AI, no comment
checking — if the label is still there past its timeout, close it.
Removing a label (by a triager, slash command, or future AI retriage)
is what prevents closure.

Each close message directs the reporter to open a new issue rather
than engaging with the closed one.

The script supports --dry-run for local testing:
  GITHUB_TOKEN=$(gh auth token) \
  GITHUB_REPOSITORY_OWNER=anthropics \
  GITHUB_REPOSITORY_NAME=claude-code \
  bun run scripts/sweep.ts --dry-run

## Test plan

Ran --dry-run against anthropics/claude-code. Correctly identified 3
issues past their timeouts (1 needs-repro at 12d, 2 needs-info at
14d and 26d). No false positives.
