Add maxLevel field to ThinkingSupport interface to cap reasoning
effort at model's maximum supported level. This fixes Issue #344
where gpt-5-mini fails with xhigh reasoning (only supports high).
- Add Codex provider to model catalog with gpt-5.2-codex and gpt-5-mini
- Add capLevelAtMax() and capEffortAtModelMax() for runtime capping
- Update UI presets with new Codex models and tier mappings
* feat(cliproxy): add HTTPS tunnel for remote proxy mode
Claude Code doesn't support HTTPS in ANTHROPIC_BASE_URL directly (undici
limitation). This adds an HTTP→HTTPS tunnel proxy for remote CLIProxyAPI
connections.
Changes:
- Add HttpsTunnelProxy: local HTTP server tunneling to remote HTTPS
- Add CodexReasoningProxy HTTPS support and path prefix stripping
- Remote mode now uses root paths (/v1/messages) not provider-prefixed
- Add remote token uploader for syncing OAuth tokens to remote server
- Auto-upload tokens after OAuth auth when remote mode is enabled
Flow for remote HTTPS:
Claude CLI → CodexReasoningProxy → HttpsTunnel → Remote HTTPS

* fix: add timeout to flaky npm CLI tests
Tests 'handles empty arguments gracefully' and 'handles very long argument'
were missing timeout option in execSync, causing occasional timeouts when
bun test's 5000ms limit was reached before CLI completed.
