fix(models): catalog ids, Claude [1m] suffix, auto = most used

[duyet]

Summary

• Config and non-Claude agents store/send catalog ids (stealth/ox-alpha). Claude Code spawn appends [1m] (1M context); Claude strips it before the gateway so Pi/Codex never see the suffix.
• Unset / auto default resolves to GET /v1/models?sort=usage (most used this week). A user-pinned model is kept. Settings x (or picking auto) clears back to that.

Test plan

• cargo test
• anyr claude --dry-run --model stealth/ox-alpha shows ANTHROPIC_MODEL=stealth/ox-alpha[1m]
• anyr pi --dry-run --model stealth/ox-alpha[1m] passes --model stealth/ox-alpha
• Config x on default model resets to auto (most used)

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	2.3 MiB	3.05 ms	2.8 ms
anyr-linux-arm64	native	2.3 MiB	0.69 ms	0.76 ms
anyr-linux-x86_64	native	2.6 MiB	0.8 ms	0.8 ms
anyr-windows-x86_64.exe	native	2.2 MiB	9.15 ms	9.15 ms
anyr.wasm	wasm	173.9 KiB	—	—

Budget check: ok
