Map entries may now carry a menu description (/cmd::desc=bash) shown in
the bot's "/" menu; it falls back to the bash command (~40 chars) when
omitted. The command list is pushed automatically after every map edit,
on --enable, and at daemon start, plus a manual --sync-commands flag
(wired into POS_FLAGS completion). Names are validated against Telegram's
lowercase [a-z0-9_] rule — invalid ones are skipped from the menu with a
warning but still resolve when typed; an empty map clears the menu.
Fixes found by unit-testing the sync path: map_has always returned false
(awk END{exit 1} overrode the match), map_set had a local cross-reference
that broke under set -u, and warn() leaked into the generated JSON (now
stderr). Docs + AGENT_TODO updated; make gen && make check pass.
The --send flag duplicated the send subcommand — completion suggested both.
Now 'pos communication telegram <TAB>' completes to just 'sender' and
'listener'. send is the single canonical action.
- git mv bin/pos-communication-telegram bin/pos-communication-telegram-sender
- remove --send branch + POS_FLAGS entry; add --markdown to completion
- lib/notify.sh: notify_sender_name() maps platform telegram -> telegram-sender
(notify_send otherwise looks for bin/pos-communication-telegram)
- pos-system-health --send 'sent:' check + pos-entertainment-send use the new
name and the send subcommand
- completion: keys with nested tools but no direct tool complete to the group
suffixes (sender/listener); --type/--parse-mode value completion moved to
the new word positions
- docs updated (POS.md, AGENT_Context, DEV.md, SCRIPTS.md, notify.env,
HOWTO.md, postinstall.sh); removed phantom webhook/log/broadcast subcommands
from howto/communication.md
