ci: skip excluded files when applying package labels in pr-labeler (#36114)

Browse Source 
A PR that only touches `uv.lock` currently gets the label of its' dir
because the file rule matches on the file prefix. This is misleading —
lockfile-only changes aren't meaningful package changes. The
`excludedFiles` list already existed in config (for size calculations),
but file rules didn't consult it.

## Changes
- Add `skipExcludedFiles` option to file rules in
`pr-labeler-config.json`, enabled for the four package rules
(`deepagents`, `cli`, `acp`, `evals`) so lockfile-only PRs don't trigger
package labels
- `matchFileLabels` in `pr-labeler.js` now filters out files whose
basename appears in the top-level `excludedFiles` list (currently just
`uv.lock`) before testing rules that opt in via `skipExcluded`
- Non-package rules (`github_actions`, `dependencies`) are unaffected —
they don't set the flag
