Add Meta Muse harness support

[edwin-zvs]

Summary

• add a built-in Meta Muse adapter with interactive TUI and structured headless modes
• persist and resume native Muse UUIDs, binding interactive logs by PTY child PID
• translate assistant messages, usage, model, and reasoning effort into Construct events
• register Muse in availability, configure, doctor, documentation, and harness metadata
• route follow-up input correctly for PTY-capable adapters running in headless mode

Verification

• cargo test -p construct-adapter-muse
• cargo test -p construct-daemon pty_capable_headless_session_uses_adapter_input
• cargo test --workspace
• cargo build
• installed Muse 0.1.0 echo-provider E2E: two headless turns completed under one persisted Muse UUID
• git diff --check
• rustfmt --edition 2021 --check crates/adapter-muse/src/lib.rs crates/protocol/src/adapter/pty.rs

No screenshot or recording: this adds harness plumbing and embeds Muse’s existing TUI rather than introducing a new Construct visual surface.
