Multi-Format log parser

Add a log and press Parse. The sample is JSON Lines with nested fields; every format on the list parses the same way into one field table.

Detection reads the shape of each source, so a weird file can be guessed wrong; forcing the format fixes it. Stamps that already carry an offset or a Z keep their own offset, offset-less stamps resolve against the zone you picked, IIS date and time fields read as GMT, and BSD syslog stamps carry no year at all, so they stay as raw text. The parser reads what is in the text and nothing more: it does not validate signatures, join records across sources, or tail a live stream.
