Reply-bot overhaul on top of the trigger/reply auto-reply: Robustness - single botTriggerMatches() shared by DM/channel paths; named constants (BOT_REPLY_COOLDOWN_MS / BOT_SCRATCH) replace magic numbers. - per-contact DM throttle (8-entry ring) so a second sender isn't starved while one contact is on cooldown. - channel anti-loop: skip only when an incoming message equals our own reply (was: any reply containing the trigger word — which silently killed channel replies for the common "trigger word in reply" setup). Features - away / reply-to-all: a lone "*" trigger matches every message. - independent DM vs channel triggers (bot_trigger / bot_trigger_ch); "*" works on the channel too, bounded by cooldown + echo guard. - query commands: a DM or monitored-channel message is scanned for "!word" tokens — !ping/!batt/!loc/!time/!temp/!hops/!status/!help — merged into one combined reply. DM = per-contact throttle, ignores quiet hours; channel = broadcast, per-channel cooldown, respects quiet hours. !hops uses getPathHashCount() (0 = direct). - quiet hours (bot_quiet_start/end, local, wraps midnight) silence push replies. - reply counter shown in the BotScreen header. UI / storage - BotScreen: 9 rows, scrolling list (no more cramming), field I/O via fieldBuf()/fieldCap(). - prefs bot_commands_enabled / bot_quiet_start / bot_quiet_end / bot_trigger_ch persisted; schema 0xC0DE000A → 0xC0DE000C with clamping + migration (bot_trigger_ch seeded from bot_trigger on upgrade). - docs: tools_screen bot section rewritten; FEATURES.md refreshed.
