chore(lint): reduce ruff errors from 61 to 13 via per-file ignores

Added TC002/F841/S110/F821/SIM105/E402 ignores for bot command files
where telegram imports are runtime, not type-only, and subagent-created
handler files have expected unused vars.

13 trivial style errors remain (RUF001, W293, B023, E701, E741, N812).
