Uses a single `git log` command via `Deno.spawnAndWaitSync()` during Lume preprocessing to build a file-to-date map, then displays "Last updated on <date>" above the feedback section. Skips API reference and lint rule pages. Closes #1280. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

- The `actions/checkout@v4` defaults to `fetch-depth: 1` (shallow clone), so the `git log` command added in #2982 only sees a single commit and almost no files get a `lastModified` date - Adding `fetch-depth: 0` gives the preprocessor full git history to build the file→date map Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Deno Deploy's GitHub integration does a shallow clone, so the `git log` approach from #2982 produces no data at deploy time. Instead, generate lastModified.json from git history as a build step and commit it via CI. The Lume preprocessor now reads from this JSON file instead of spawning git.
