feat: F_GETPIPE_SZ/F_SETPIPE_SZ pipe capacity control via fcntl

- F_GETPIPE_SZ returns current pipe buffer capacity
- F_SETPIPE_SZ resizes pipe buffer (min 512, max 65536)
- Linearizes ring buffer data during resize
- Returns EBUSY if new size < current data count
- Added EBUSY errno (16)
- 35/35 smoke tests pass, cppcheck clean
