Evan c63bfb6d94 Exempt Dependabot PRs from the PR gate (#4395)
## What

Adds a trusted-bot exception to the PR gate so Dependabot's PRs are no
longer auto-closed.

## Why

The PR gate (`scripts/pr-gate/`, run by `.github/workflows/pr-gate.yml`)
auto-closes PRs that don't fit the contribution workflow. Dependabot PRs
were getting closed because the bot:

- has no repo permission,
- links no `approved` issue, and
- opens dependency bumps that often exceed the 50-line small-fix cap.

## How

- `config.ts` — new `TRUSTED_BOT_AUTHORS` constant (currently
`["dependabot[bot]"]`), so the allowlist is easy to extend.
- `rules.ts` — new `checkTrustedBot()` rule, wired into `evaluate()`
right after the maintainer bypass and before the repo-access check.
- `tests/PrGateRules.test.ts` — unit tests for the rule plus an
`evaluate()`-level test proving a 5000-line Dependabot PR now passes
instead of closing.
- `README.md` — documented the new rule in the gate-logic ordering.

The match is exact, so a lookalike login (e.g. `not-dependabot[bot]`)
won't slip through. Add more bots (Renovate, etc.) to
`TRUSTED_BOT_AUTHORS` as needed.

## Testing

`npx vitest tests/PrGateRules.test.ts --run` → 39 passed. Lint +
prettier clean.

This PR was automatically closed because it doesn't fit our contribution workflow:
- You aren't currently assigned to an issue labelled \`${APPROVED_ISSUE_LABEL}\`, **and**
- The change is larger than ${SMALL_FIX_LINE_THRESHOLD} lines (our cap for unsolicited contributions).
**To contribute to OpenFront:**
1. **For bugs or small quality-of-life improvements:** open an [issue](https://github.com/${REPO.owner}/${REPO.repo}/issues/new/choose). A maintainer will label it \`${APPROVED_ISSUE_LABEL}\` if it's something we'll work on.
2. **For feature ideas:** discuss in the [dev Discord](https://discord.gg/K9zernJB5z) first. We don't accept unsolicited feature PRs — even if they're good ideas, every merged feature is a permanent maintenance burden.
3. **Once an issue is labelled \`${APPROVED_ISSUE_LABEL}\`**, comment asking to be assigned. After you're assigned, you can open a PR referencing that issue.
If you believe this was closed in error, please reach out on our [Discord](https://discord.gg/K9zernJB5z) or comment below.
See [CONTRIBUTING.md](https://github.com/${REPO.owner}/${REPO.repo}/blob/main/CONTRIBUTING.md) for the full contribution process.
