/api/inspector/sessions/:id/property serves CaptureProperty's worlds, built
once per loaded capture on a worker after the replica pass, with the zone's
and the models' names from the locale and the property saved now for each
zone and clone (read on the main thread) for links and UGC meshes.

Links the game for its message structs, reads the components of every LOT at startup, and decodes a capture's
replica packets once, in timeline order, on a worker thread.

/api/inspector/sessions/:id/worlds lists the captured characters' moves between
world servers with the zone's name from the locale; /positions also returns them,
takes ?zone=all and names each track's character and zone.

The Packet Captures page (/inspector/packets, dev_message_inspector) arms captures with a
search picker (part of an account or character name, or a pasted account or object ID; online
ones marked; everything needs no pick), lists running and saved ones live (packet_capture
topic), and plays one back on its timeline: play, pause, seek and speed, packets appearing in
order with their decoded fields and bytes. World 3D takes ?capture=<id>&zone=<zone> and replays
the captured position updates in its replay mode; the capture page's playhead drives it over a
BroadcastChannel. Saved packet captures show in the Message Inspector's list and open there.

Staff arm a packet capture on the dashboard; master passes MESSAGE_CAPTURE_CONTROL ARM to
every world, auth and chat and arms its own. Each server's PacketCapture tap (dServer receive,
and a send hook in RakPeer::Send so replica constructions are seen too) records into one
preallocated chunk per server and ships sealed chunks through master on the main loop when
capture_flush_bytes or capture_flush_interval_ms is reached; past capture_buffer_max_mb the
oldest chunks are dropped and the dashboard records a gap. Nothing is armed: one flag check.
- targets: an account (from its login; packets before the login are kept per connection
and added once auth or the world knows whose they are), a character (from when it is
picked), or everything; up to 8 at once (a bit each in the record mask)
- worlds and auth record their clients' packets and the master link messages of a captured
player (session keys by name, zone transfers by request, player added/removed, migration);
chat finds the player in each packet; master records server traffic for everything
- secrets are never recorded: structs that carry them (login request, login response user
key, world validation session key, session key messages between servers) are read,
blanked and written again before recording; auth keeps only the handshake and login
- PacketDecoder: a registry by service and message id names every packet and decodes the
registered structs; CaptureBundle is the file format (DLUBNDL1, metadata, records);
CaptureTools orders records on one timeline, pulls movement out, makes bundles portable
or anonymous and diffs replays
- the dashboard keeps packet captures in message_capture_sessions (capture_kind 1) and
their packets in a file under capture_dir, one write per batch; arming is audited
- MESSAGE_CAPTURE_CONTROL/DATA only gain appended enum values and trailing fields
