kshitijk4poor 214e60c951 fix: sanitize Telegram command names to strip invalid characters ...

Telegram Bot API requires command names to contain only lowercase a-z,
digits 0-9, and underscores. Skill/plugin names containing characters
like +, /, @, or . caused set_my_commands to fail with
Bot_command_invalid.

Two-layer fix:
- scan_skill_commands(): strip non-alphanumeric/non-hyphen chars from
  cmd_key at source, collapse consecutive hyphens, trim edges, skip
  names that sanitize to empty string
- _sanitize_telegram_name(): centralized helper used by all 3 Telegram
  name generation sites (core commands, plugin commands, skill commands)
  with empty-name guard at each call site

Closes #5534
