Tune the TX power of a remote node we have admin rights on (the hop before
a chosen target) to maximize the SNR the target receives from it, instead of
tuning the local device against a path bottleneck.
- Device gains admin_login / get_remote_tx_power / set_remote_tx_power
(MeshCoreDevice via send_login_sync + `set tx <dbm>` send_cmd; MockDevice
models target SNR as an inverted-U in the admin node's TX with a reliability
dropoff at the band edges).
- tx_optimizer: forced-path sweep with a lexicographic objective (reliability
first, then SNR), median-based levels, coarse+refine search, and a verify
pass; near-SNR ties break toward lower power. Outlier-robust by construction.
- AdminStore remembers per-node admin passwords in <config_dir>/admin.json
(owner-only perms), cleared automatically when a login is rejected.
- Configurable 12-28 dBi default range (tx_opt_min/tx_opt_max).
- tx-optimize tool: path/password prompts, live progress, persistence, applies
the winner on finish, and renders an interactive HTML chart.
- Rewrote TX result models, widgets, plot, repository.record_tx_sample, and the
TX tests for the new flow.

Trace:
- Auto-path now ends every route at the target's own hash (verified on
hardware: a trace only replies when its destination is the final hop), so
direct neighbors and learned multi-hop routes both resolve correctly.
- Retry the transient "no event received during contacts retrieval" blip and
surface a clean DeviceCommandError instead of a raw traceback.
- Route summary annotates each node with its hash at the command's path-hash
width, wrapping after an arrow when the line is too long.
- Default trace count changed from 5 to 3.
Also includes the in-progress device-config feature (config_io, device_config,
config tool, config editor UI, tests) and related supporting edits.

MeshTools is a Rich+Questionary interactive / Typer-scriptable toolkit for
tuning a MeshCore mesh over a serial companion device, with SQLite-logged runs
and Plotly visualizations. Includes the skeleton (trace, info, history),
TX-power optimization, and a MockDevice simulator (--mock).
Device discovery & selection:
- core/discovery.py: enumerate serial ports (pyserial), flag/sort likely LoRa
hardware by USB vendor id, stable_id for replug-safe identity.
- core/device_store.py: remember the last successfully connected device in
<config_dir>/devices.json (independent of --db).
- core/selection.py: non-interactive resolver (--port > profile > remembered >
sole device > guidance error) for the CLI.
- ui/device_picker.py + menu startup: interactive picker preselecting the
remembered default; banner reflects the choice.
- tools/devices.py: `meshtools devices` lists/marks attached devices.
- AppContext resolves the port and records last-known-good on connect success.
Fixes:
- theme.py: force UTF-8 on stdout/stderr so glyphs don't crash legacy consoles.
- connection.py: friendly message when meshcore is missing; pin meshcore>=2.3.
- trace/tx-optimize: fall back to free-text target entry when the device
reports no contacts (autocomplete requires non-empty choices).
