Fix critical logic and boundary bugs in read_proc_maps_line() and caller. Ensure any mid-line hex/dec/char parsing failure invokes io__drain_line() safely, using a do-while loop to read and discard remaining characters until a newline or EOF is reached. Clamp pathname extraction size to account for trailing sample ID headers, use standard '//toolong' fallback literal for over-length pathnames, emit timeout flags for truncated entries securely via goto out;, and cast event buffer pointers to avoid _FORTIFY_SOURCE array bounds aborts across synthesis handlers.
