Implement fsck integrity verification (#2)

## Summary - Add `Fsck.check/2` with `:full` and `:quick` modes for repository integrity verification - Add `list_objects/2` callback to Storage behaviour, implemented in all three backends - Full mode verifies: loose object SHA integrity, object graph completeness, ref validity, pack checksums - Quick mode verifies: ref validity and graph reachability only Closes #14 ## Changes - **lib/ex_git_objectstore/fsck.ex** — New module with `check/2` entry point - **lib/ex_git_objectstore/storage.ex** — Added `list_objects` callback - **lib/ex_git_objectstore/storage/{memory,filesystem,s3}.ex** — `list_objects` implementations - **test/support/tracking_memory.ex** — Added `list_objects` delegation - **test/ex_git_objectstore/fsck_test.exs** — 11 tests covering all acceptance criteria ## Test plan - [x] Valid repo returns clean report - [x] Detects corrupted object data (SHA mismatch) - [x] Detects missing object referenced by tree - [x] Detects missing parent commit - [x] Detects dangling ref - [x] Detects corrupted pack checksum - [x] Detects missing tag target - [x] Quick mode detects dangling ref but skips SHA verification - [x] Report includes counts - [x] All 540 tests pass, dialyzer clean
