fix(cli): keep TUI keys, tool yaml, and relay from dropping state

[duyet]

Summary

• Shift-Tab (BackTab) now cycles settings tabs; unknown Ctrl no longer quits.
• PATH misses are not cached, so --install can see the new binary.
• Partial tools: YAML no longer wipes gateway discovery or /v1; extra (including yolo) round-trips and launch honors it.
• Claude spawn sets ANTHROPIC_API_KEY so a parent-shell key cannot win.
• Relay pairing returns the minted token instead of panicking on re-read; worker spawn failure is an Error frame.

Checklist

• Version stays on 0.1.x (do not introduce 0.2 / 1.0)
• Do not auto-merge release-please PRs

anyr size and startup

Startup is wall time for a cold anyr --version / anyr --help (median of 21 runs). Size is the stripped release binary, or the .wasm for the browser demo.

Size budget: anyr-linux-x86_64 must stay ≤ 4.0 MiB (4194304 bytes) stripped.

Asset	Kind	Size	--version median	--help median
anyr-darwin-arm64	native	2.8 MiB	3.5 ms	3.02 ms
anyr-darwin-x86_64	native	3.0 MiB	44.63 ms	44.3 ms
anyr-linux-arm64	native	2.8 MiB	0.86 ms	0.87 ms
anyr-linux-x86_64	native	3.1 MiB	0.96 ms	0.94 ms
anyr-windows-x86_64.exe	native	2.6 MiB	6.89 ms	6.97 ms
anyr.wasm	wasm	176.0 KiB	—	—

Budget check: ok
