fix: fit all 100 commands in Telegram menu with 40-char descriptions (#4010)

* fix: truncate skill descriptions to 100 chars in Telegram menu

* fix: 40-char desc cap + 100 command limit for Telegram menu

setMyCommands has an undocumented total payload size limit.
50 commands with 256-char descriptions failed, 50 with 100-char
worked, and 100 with 40-char descriptions also works (~5300 total
chars). Truncate skill descriptions to 40 chars in the menu picker
and set cap back to 100. Full descriptions available via /commands.
