Ultraworked with [Sisyphus](https://github.com/code-yeongyu/oh-my-opencode)

Co-authored-by: Sisyphus <clio-agent@sisyphuslabs.ai>

* feat(mcp-oauth): add RFC 7591 Dynamic Client Registration

* feat(mcp-oauth): add RFC 9728 PRM + RFC 8414 AS discovery

* feat(mcp-oauth): add secure token storage with {host}/{resource} key format

* feat(mcp-oauth): add dynamic port OAuth callback server

* feat(mcp-oauth): add RFC 8707 Resource Indicators

* feat(mcp-oauth): implement full-spec McpOAuthProvider

* feat(mcp-oauth): add step-up authorization handler

* feat(mcp-oauth): integrate authProvider into SkillMcpManager

* feat(doctor): add MCP OAuth token status check

* feat(cli): add mcp oauth subcommand structure

* feat(cli): implement mcp oauth login command

* fix(mcp-oauth): address cubic review — security, correctness, and test issues

- Remove @ts-nocheck from provider.ts, storage.ts, provider.test.ts
- Fix server resource leak on missing code/state (close + reject)
- Fix command injection in openBrowser (spawn array args, cross-platform)
- Mock McpOAuthProvider in login.test.ts for deterministic CI
- Recreate auth provider with merged scopes in step-up flow
- Add listAllTokens() for global status listing
- Fix logout to accept --server-url for correct token deletion
- Support both quoted and unquoted WWW-Authenticate params (RFC 2617)
- Save/restore OPENCODE_CONFIG_DIR in storage.test.ts
- Fix index.test.ts: vitest → bun:test

* fix(mcp-oauth): use explorer instead of cmd /c start on Windows to prevent shell injection

* fix(mcp-oauth): address remaining cubic review issues

- Add 5-minute timeout to provider callback server to prevent indefinite hangs
- Persist client registration from token storage across process restarts
- Require --server-url for logout to match token storage key format
- Use listTokensByHost for server-specific status lookups
- Fix callback-server test to handle promise rejection ordering
- Fix provider test port expectations (8912 → 19877)
- Fix cli-guide.md duplicate Section 7 numbering
- Fix manager test for login-on-missing-tokens behavior

* fix(mcp-oauth): address final review issues

- P1: Redact token values in status.ts output to prevent credential leakage
- P2: Read OAuth error response body before throwing in token exchange
- Test: Fix mcp-oauth doctor test to use epoch seconds (not milliseconds)
