Commit Message

perf: Implement eager lookahead buffering in reader

The `runeReader` now implements an eager replenishment strategy to
maintain a lookahead buffer. Instead of reading one rune at a time from
the underlying `io.Reader`, it now reads in chunks.

This change reduces the number of system calls and improves parsing
performance on large inputs.

- The `BufferedLength()` method's semantic was changed to return the
  absolute index of the buffer's end.
- The syslog parser example was significantly improved to better
exercise
  the new reader logic.
- A fix was included to properly propagate `io.EOF` as a failure cause.
