Add benchmark suite and results
...
Benchmark harness (benchmarks/run_benchmarks.py):
- Mount time, readdir, stat latency, file open/read, memory usage
- ENOENT lookup (missing file) benchmark per Oracle review
- Uses synthetic FLAC files from test infrastructure
Results: ALL BENCHMARKS BLOCKED BY BUGS
- Bug #2 (directory tree building) crashes mount with any content
- FSNode.adddir() assumes parent dirs exist, fails with KeyError
- Bug #1 (nested methods) would block FUSE ops even if mount worked
beetfs is non-functional for real-world use until both bugs fixed.

Add benchmark plan for beetfs performance measurement
...
Covers:
- Mount time scaling (100 to 100K items)
- Metadata operations (stat, readdir throughput)
- File I/O (open latency, read throughput)
- Memory usage (idle, per-file, leak detection)
- Concurrent access (GIL impact)
- Realistic workloads (library scan, album playback)
Tools: fio, mdtest, hyperfine
Baselines: ext4, fuse-passthrough, sshfs
Key bottlenecks identified:
- FileHandler loads entire file into RAM on open
- Mount-time bulk load of all library items
- Python GIL limits parallelism

Document test findings and fix mount script
...
Test Results (74 tests):
- 12 passed, 56 failures, 3 errors, 3 skipped
Bugs Detected:
1. Nested methods bug: lines 758-1144 indented inside access()
- FUSE operations (readdir, open, read, write) unreachable
- os.listdir() returns ENOSYS (Function not implemented)
2. Directory tree building: KeyError in FSNode.getnode()
- Mount fails when library contains tracks
3. Unmount not clean: filesystem not releasing properly
Changes:
- Fix conftest.py: inline sanitization (no module-level sanitize fn)
- Add test findings to e2e-test-plan.md
- Add .gitignore for .pyc and test artifacts

Add e2e test suite for beetfs
...
Tests use real FUSE operations against mounted beetfs filesystem:
- test_smoke: mount/unmount lifecycle
- test_nested_bug: detects critical indentation bug (13 failures)
- test_readdir: directory listing
- test_read: metadata overlay verification
- test_stat: file/directory attributes
- test_write: metadata modification
- test_error_handling: ENOENT, EOPNOTSUPP
Also includes:
- conftest.py with BeetFSTestCase base class and synthetic FLAC generator
- e2e-test-plan.md with Oracle-reviewed test strategy
- flake.nix updated with ffmpeg/flac for test fixtures
Run: cd tests && nix develop ../ --command python -m unittest discover
