feat: Allow unknown slash commands to passthrough to Claude Code in agentic mode

[HaqimIskandar]

Problem

In agentic mode, unknown slash commands (e.g., /workflow, /skill, /add-memory) are ignored or error because they're not registered as Telegram bot commands.

Solution

Remove & ~filters.COMMAND\ filter from the agentic text handler so ALL text messages (including unknown slash commands) are passed through to Claude Code.

Change

\\python

Line ~320 in src/bot/orchestrator.py

OLD:

filters.TEXT & ~filters.COMMAND

NEW:

filters.TEXT
\\

Result

• Existing commands still work: /start, /new, /status, /verbose, /repo\ (higher priority CommandHandler)
• Unknown slash commands now passthrough: /workflow activate job-hunter, /skill use resume-optimizer, /add-memory\
• Natural conversation continues to work (no slash commands)

Testing

Test created: \ ests/test_orchestrator_passthrough_simple.py
Test passes: Verifies \ilters.TEXT\ is used, not \ilters.TEXT & ~filters.COMMAND\
