Xe Iaso feat(s3fs): cache immutable pack files on local disk to fix clone hangs 2mo ago

feat(s3fs): cache immutable pack files on local disk to fix clone hangs Serving a clone via upload-pack's delta-compression re-reads pack objects thousands of times. Commit 76bb55d made pack reads lazy to avoid RAM buffering; this causes each access to issue a fresh S3 GetObject, making real-repo clones never finish. Implement PackCache: immutable pack-dir files (.pack/.idx/.rev) download once to a local temp file (LRU-bounded by -pack-cache-bytes, default 2GB) and all reads serve from local disk. Results on real Tigris bucket: - objgit (318 objects, 200KB pack): 8500+ GetObjects → 10, 7s - kefka (197 commits, 19.6MB pack): hang → 14s, full clone The cache is wired into OpenFile and shared across Chroot children like the listing cache. Add flags: -pack-cache-bytes, -pack-cache-dir. See docs/plans/pack-temp-file-cache.md for design. Assisted-by: Claude Opus 4.8 via claude.ai Signed-off-by: Xe Iaso <me@xeiaso.net>

feat(s3fs): add optional Unix-metadata storage as S3 user metadata Store POSIX file attributes (uid, gid, mode, mtime) as x-amz-meta-* headers on S3 objects so POSIX filesystems layered on Tigris can round-trip ownership and permissions instead of always reporting mode 0666 with no owner. The feature is opt-in and off by default: NewS3FS takes functional options, and without WithUnixMetadata the filesystem behaves exactly as before. Callers opt in by passing WithUnixMetadata(uid, gid, umask) and resolve any name strings to numeric IDs themselves. New unixmeta package implements Encode/Decode and PosixMode/GoFileMode conversion; the wire format is documented in docs/reference.
