fix(cli): anyrouter/auto[1m] stays auto with min_context

[duyetbot]

Fixes #65

anyr claude --model anyrouter/auto[1m] now:

• keeps ANTHROPIC_MODEL=anyrouter/auto (not Laguna)
• sends CLAUDE_CODE_EXTRA_BODY provider.min_context: 1000000
• turns off gateway model discovery for auto so Claude Code cannot remap the virtual id

Gateway sibling: duyet/anyrouter#3294

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	5.47 ms	3.97 ms
anyr-darwin-x86_64	native	3.0 MiB	39.81 ms	37.73 ms
anyr-linux-arm64	native	2.8 MiB	0.69 ms	0.69 ms
anyr-linux-x86_64	native	3.1 MiB	0.99 ms	0.99 ms
anyr-windows-x86_64.exe	native	2.6 MiB	9.41 ms	9.91 ms
anyr.wasm	wasm	177.7 KiB	—	—

Budget check: ok
