v0.46.3 — Computer Runtime compatibility fixes

Computer Runtime compatibility fixes with the existing install-then-pair workflow preserved.

• Include python-socks[asyncio] in the Computer extra for WebSocket proxy support.
• Identify HTTP/WebSocket requests with Nexus-Computer/0.46.3.
• Fix browser Enter input on macOS/Linux pipe-based terminals; retain Windows behavior.
• Include the Linux IPv6 service group fix from the previous source revision.
• Add macOS CI and regression coverage.

Download the wheel, activate the same environment used by Runtime, then run:

python -m pip install --upgrade "./nexus_openwrt_agent_sdk-0.46.3-py3-none-any.whl[computer,browser]"
nexus-computer restart
nexus-computer status

Keep existing configuration and device keys; no re-pairing is required. New computers still install Runtime before pairing. Packages are distributed here on GitHub, not PyPI.

Runtime fixes adapted from Nexus Cloud Community PR #5. This release does not include its generated installer or installed-package monkeypatches. POSIX terminals still use pipes rather than a PTY. Local Linux and Windows verification does not establish real macOS launchd or system-proxy acceptance.

Validation: all seven CI jobs passed, including Python 3.12/3.14 on macOS, Linux and Windows plus the Python 3.9 core installation. Fresh Linux wheel installation, dependency checks and command entrypoint verification also passed.
