Make /help dynamic and re-sync the bot menu

/help now re-runs setMyCommands so late-registered pi commands (skills,
prompts, extensions that registered after /start) become discoverable
without restarting the bridge, and prints the live pi.getCommands() list
so the user can see what's actually wired up right now.

Addresses the symptom where the Telegram command menu sometimes shows
only the bridge-local commands - a registration-order race against the
initial setMyCommands at /start.
