ingest::run_file tails a path like tail -f: reads existing content,
follows appended lines, and detects file recreation/truncation (via
inode on unix, or a shrinking size) to resume tailing the new
instance from its start instead of exiting or stalling. Sequence
numbers keep incrementing across a recreation event since they're
ottyl's own line counter, not tied to the source file. stdin ingest
is unchanged and remains the default when --file is omitted.
