Drop INVALID and UNRELIABLE packets per PROTOCOL.md quality grading
to avoid retransmitting likely-corrupt data. MARGINAL packets are
forwarded with a warning tag. All RX log lines now include SNR.

- Add cargo-binutils to mise.toml (needed for `just size`)
- Remove jj from mise.toml (optional, not a build dependency)
- Silence `mise install` output when tools are current (--quiet)
- Add `just outdated` recipe with embassy-executor exclusion
(esp-rtos 0.2 pins embassy-executor ^0.9; 0.10 renamed arch-*
features to platform-*, which crashes cargo-outdated)

Audited against meshcore-spec and fixed all compliance gaps:
- Fix trace hash size encoding: use 1<<(flags&3) not (flags&3)+1
- Reject reserved path hash_size_code 3 per spec Section 3
- Minimum packet size 3 bytes (was 2)
- Add MAX_PACKET_PAYLOAD (184) and min payload (1) validation
- Tighten payload minimums: ANON_REQ≥51, encrypted≥20, group≥19,
multipart≥2
- Add node_type 0 ("none") to NODE_TYPES
- Fix node_type fallback display (was "node=type=14", now "node=0x0e")
Add packet quality warnings for likely-corrupt frames:
- decode_meshcore_packet returns (str, list[str]) with quality warnings
- ADVERT: flag bad node_type, bad UTF-8 in name, future/bad timestamps
- Combine content warnings with low-SNR signal at display layer
- Warnings stack: one flag = maybe, multiple = high confidence corrupt
Update test corpus and generators for tightened validation rules.

These paths are already in .gitignore but were committed before the
ignore rules existed. Remove them from the index so they stay local.

Replace raw dict dumps and debug-style prints with consistent
themed output using >>> / <<< markers and formatted responses.
Quiet TxDone noise, dim status messages, and align all output
with the 2-space indent used by RX packet lines.
New protocol command (tag 8): GetMac returns the board's 6-byte hardware
address. Useful when multiple dongles are connected to one host.
Response (tag 6): MacAddress containing 6 raw bytes.
Updated: PROTOCOL.md, CHANGELOG, donglora.py decoder, all_commands.py.
Config response (GetConfig) now returns decoded RadioConfig fields instead
of raw hex. New all_commands.py exercises all 8 protocol commands in
sequence — Ping, SetConfig, GetConfig, StartRx, StopRx, Transmit,
DisplayOff, DisplayOn.
All examples now catch serial.SerialException instead of crashing with
a traceback. This covers port contention (multiple processes), device
disconnect, and USB errors. meshcore_rx.py already had this.
Remove all varint/zigzag encoding. Every field is now struct.pack/unpack
with fixed-size little-endian format strings. RadioConfig is a single
struct.pack('<IBBBHB', ...) call. Response decoding uses struct.unpack_from
with known offsets. No encoding helpers needed beyond struct.
- Each board exports TX_POWER_RANGE constant (min, max dBm)
- RadioConfig::validate() uses the board's range, not hardcoded limits
- TX_POWER_MAX sentinel (-128 on the wire) means "use board's maximum"
— resolved to the actual max before storing config
- GetConfig returns the resolved actual power, not the sentinel
- Default configs in examples use TX_POWER_MAX
- Protocol docs updated
ROOT CAUSE: postcard encodes u8 and i8 as raw bytes, NOT varint/zigzag.
The Python encoders used varint() for u8 and zigzag() for i8. For small
values this was silently correct (varint(7) == raw byte 7), but for
tx_power_dbm: zigzag(14) = 28, which the new validation correctly
rejected as out of range (-9..22). This was a pre-existing bug masked
by the absence of validation.
Fix all RadioConfig field encoders in both donglora.py and meshcore_rx.py.
Fix docs/PROTOCOL.md to correctly document i8 as raw byte, not zigzag.
Restore full config validation.
MeshCore is a protocol implementation ON TOP of DongLoRa, not part of the
dongle itself. Moving it to examples/ makes the separation clear while
keeping it accessible as a real-world usage example.
