Each attempt waited only for its own tag, so a reply that arrived after its attempt's timeout was dropped once the retry went out. On my test mesh a three-hop trace takes about nine seconds (each repeater waits its random TX delay before forwarding), against a 2.5 s timeout, so every trace failed even though the first attempt's full reply came back.
run_trace now subscribes to TRACE_DATA once, before the first send, and takes a reply to any of its tags until the last attempt's timeout runs out. A reply that lands during the retry delay ends the trace without sending again, and subscribing before the send also closes the window where a fast reply could arrive before wait_for_event was listening.
The timeout defaults go from 1.0 s base and 0.5 s per hop to 2.0 s and 1.5 s, matching the 1.5 s the trace command and its settings schema already used. Configs that set them keep their values.
match_packet_hash gave a pending transmission the hash of the first packet heard within its 30-second window, whatever the packet was. On a busy mesh that was usually someone else's message or advert, so its repeats were counted as ours (the web viewer's repeat counts, DARC MoWaS's ACK check, graph_trace_helper's "our trace" test) and our real repeats were not.
A transmission now records what identifies its packet (the channel index for a channel message, the recipient's key for a DM, the tag for a trace) and match_packet_hash claims it only for a packet carrying the same: a GRP_TXT that decrypts on that channel to the same text, a TXT_MSG addressed to the recipient's hash and, when the radio's key is known, from ours, or a TRACE with the same tag. The RX handler passes that evidence through _transmission_evidence, reusing the authenticated channel decode. Without evidence, match_packet_hash only looks up hashes already matched, so record_repeat and graph_trace_helper no longer claim pending transmissions.
Repeat-count writes go to a single worker thread instead of running sqlite on the event loop, and _update_command_in_database no longer inserts into sys.path on every repeat.
bot_prefix still reads meshcore.device and stays None; fixing it turns on graph_trace_helper's trace updates, which have never run, so it is a separate change.

All modules: ruff and mypy cleanup applied (type annotations, imports)
- Introduced `[Trace_Command]` section in `config.ini.example` to enable link diagnostics with customizable parameters such as maximum hops, trace mode, and retry settings.
- Updated `command-reference.md` to include usage instructions and examples for the new `trace` and `tracer` commands, detailing their functionality for manual and round-trip tracing.
- Enhanced `mesh_graph.py` to support 2-byte trace confirmation for improved path weighting.
- Modified `message_handler.py` to update the mesh graph based on trace data, ensuring accurate edge representation in the graph.
- Added translations for the new trace commands in `en.json` to support user interaction in multiple languages.
