fix(copaw): harden Matrix channel routing

[shiyiyue1102]

Summary

• require Matrix group-room control commands to be explicitly mentioned and slash-prefixed
• route reasoning/tool progress into task threads while keeping final replies visible in the main room
• suppress NO_REPLY and cancellation noise in CoPaw Matrix output

Validation

• python3 -m py_compile copaw/src/matrix/channel.py copaw/tests/test_channel_mention.py
• git diff --check

uv run --python 3.11 --project copaw pytest tests/test_channel_mention.py was attempted locally but could not build python-olm==3.2.16 on this macOS environment because its native libolm build needs unavailable/incompatible local C++ build tooling (cmake/gmake, then clang const assignment failure). GitHub CI should run the normal Linux test environment.

@maplefeng-a CI is green now. Could you take a look when convenient?

[maplefeng-a]

CI is green and the CoPaw-scoped change looks good under the agreed review policy. Approving.
