Add comment noting _EXEC_REQ_ID/_MARKER_REQ_ID are arbitrary client-chosen
values unrelated to SERVERDATA_* packet-type constants. Update _connect_and_auth
docstring to accurately reflect that OSError/socket.timeout propagate raw from
post-connect send/recv, while only connect failure is wrapped in RconError.

Extracts _connect_and_auth helper from query_status, adds execute_command
using the trailing-marker pattern for multi-packet reassembly, and covers
all paths (happy path, multi-packet, empty reply, auth failure, timeout,
input validation, marker drain) with 10 new tests.

- _parse_duration wraps int() in try/except so malformed connected
durations raise RconError (not ValueError leaking past the poller's
except RconError).
- fake_rcon_server captures handler exceptions and re-raises at context
exit, so a buggy test handler surfaces as a real failure instead of
silently degrading into a client-side timeout.
- Two new parser tests: HH:MM:SS duration parsing and malformed input
coverage.
- Fix Steam ID formula typo in the spec doc (Z*2 + Y, not Y*2 + Z; Y is
the low bit). Code was already correct.
