feat(proxy): centralize proxy handling with `proxyutil` package and enhance test coverage
- Added `proxyutil` package to simplify proxy handling across the codebase.
- Refactored various components (`executor`, `cliproxy`, `auth`, etc.) to use `proxyutil` for consistent and reusable proxy logic.
- Introduced support for "direct" proxy mode to explicitly bypass all proxies.
- Updated tests to validate proxy behavior (e.g., `direct`, HTTP/HTTPS, and SOCKS5).
- Enhanced YAML configuration documentation for proxy options.
SetOAuthSessionError previously sent generic messages to the management
panel (e.g. "Failed to complete Gemini CLI onboarding"), hiding the
actual error returned by Google APIs. The specific error was only
written to the server log via log.Errorf, which is often inaccessible
in headless/Docker deployments.
Include the upstream error in all 8 OAuth error paths so the
management panel shows actionable messages like "no Google Cloud
projects available for this account" instead of a generic failure.
- Add 'github-user' fallback in WaitForAuthorization when FetchUserInfo
returns empty Login (fixes malformed 'github-copilot-.json' filenames)
- Standardize Web API file name to 'github-copilot-<user>.json' to match
CLI path convention (was 'github-<user>.json')
Addresses Gemini Code Assist review comments on PR #291.
- Expand OAuth scope to include read:user for full profile access
- Add GitHubUserInfo struct with Login, Email, Name fields
- Update FetchUserInfo to return complete user profile
- Add Email and Name fields to CopilotTokenStorage and CopilotAuthBundle
- Fix provider string bug: 'github' -> 'github-copilot' in auth_files.go
- Fix semantic bug: email field was storing username
- Update Label to prefer email over username in both CLI and Web API paths
- Add 9 unit tests covering new functionality
- force http/1.1 instead of http/2
- explicit connection close
- strip proxy headers X-Forwarded-For and X-Real-IP
- add project id to fetch models payload
- Introduced unit tests for request logging middleware to enhance coverage.
- Added WebSocket-based Codex executor to support Responses API upgrade.
- Updated middleware logic to selectively capture request bodies for memory efficiency.
- Enhanced Codex configuration handling with new WebSocket attributes.
The delete handler now sets the channel value to nil instead of removing
the map key, and the sanitization loop preserves nil/empty channel entries
as 'disabled' markers. This prevents SanitizeOAuthModelAlias from
re-injecting default kiro aliases after a user explicitly deletes them
through the management API.
Adds explicit handling for context.Canceled errors in the reverse proxy error handler to return 499 status code without logging, which is more appropriate for client-side cancellations during polling.
Also adds a test case to verify this behavior.
