feat: implement flush-on-getPos() to ensure accurate offsets
IMPLEMENTATION:
- Added buffer flush in getPos() before returning position
- Every getPos() call now flushes buffered data
- Updated FSDataOutputStream wrappers to handle IOException
- Extensive debug logging added
RESULT:
- Flushing is working ✓ (logs confirm)
- File size is correct (1260 bytes) ✓
- EOF exception STILL PERSISTS ❌
DEEPER ROOT CAUSE DISCOVERED:
Parquet records offsets when getPos() is called, THEN writes more data,
THEN writes footer with those recorded (now stale) offsets.
Example:
1. Write data → getPos() returns 100 → Parquet stores '100'
2. Write dictionary (no getPos())
3. Write footer containing '100' (but actual offset is now 110)
Flush-on-getPos() doesn't help because Parquet uses the RETURNED VALUE,
not the current position when writing footer.
NEXT: Need to investigate Parquet's footer writing or disable buffering entirely.
