coffee c1f832a610 fix(tools): guard against ValueError on int() env var and header parsing ...

Three locations perform `int()` conversion on environment variables or
HTTP headers without error handling, causing unhandled `ValueError` crashes
when the values are non-numeric:

1. `send_message_tool.py` — `EMAIL_SMTP_PORT` env var parsed outside the
   try/except block; a non-numeric value crashes `_send_email()` instead
   of returning a user-friendly error.

2. `process_registry.py` — `TERMINAL_TIMEOUT` env var parsed without
   protection; a non-numeric value crashes the `wait()` method.

3. `skills_hub.py` — HTTP `Retry-After` header can contain date strings
   per RFC 7231; `int()` conversion crashes on non-numeric values.

All three now fall back to their default values on `ValueError`/`TypeError`.
