Will Binns-Smith 57a8476086 bundle-analyzer: record historical snapshots on each analyze run (#93520) ...

After each `next experimental-analyze` run, snapshot the output data
into a rolling `history/` directory so later builds can use it as a
comparison baseline.

Each snapshot gets a `metadata.json` with git branch/sha/dirty status,
Next.js version, and route count. A `history/history.json` index
(newest-first, capped at 20 entries) lets the UI list available
baselines without re-reading every snapshot directory. Old snapshots
beyond the cap are pruned automatically.

The client-side `SnapshotMetadata` type mirror lives in
`apps/bundle-analyzer/lib/snapshot.ts` so the compare UI can reference
it without a build-time dependency on the Next.js package.
