- test_channel_plugins: fix assertion logic for discoverable channels - test_filesystem_tools: normalize path separators for Windows - test_tool_validation: use python to generate output, avoid cmd line limits
- Add plugin discovery via Python entry_points (group: nanobot.channels) - Move 11 channel Config classes from schema.py into their own channel modules - ChannelsConfig now only keeps send_progress + send_tool_hints (extra=allow) - Each built-in channel parses dict->Pydantic in __init__, zero internal changes - All channels implement default_config() for onboard auto-population - nanobot onboard injects defaults for all discovered channels (built-in + plugins) - Add nanobot plugins list CLI command - Add Channel Plugin Guide (docs/CHANNEL_PLUGIN_GUIDE.md) - Fully backward compatible: existing config.json and sessions work as-is - 340 tests pass, zero regressions
