Add mcp/hermes.rs with bidirectional MCP format conversion:
- convert_to_hermes_format: strip type field, infer from command/url
- convert_from_hermes_format: infer type, strip Hermes-specific fields
- Merge-on-write: existing Hermes fields (tools, sampling, timeout,
roots, enabled) preserved when user has customized them
- update_mcp_servers_yaml: closure-based read-modify-write under write
lock to prevent TOCTOU races in concurrent sync operations
- 9 unit tests for format conversion and merge logic
Wire up all MCP service dispatch:
- Replace Hermes TODO stubs with real sync/remove calls
- Remove Hermes from sync_all_enabled skip list
- Enable deep link hermes MCP flag (apps.hermes = true)
- Add Hermes import to import_mcp_from_apps command
Remove dead code that was never called after v3.7.0 architecture change:
- mcp/opencode.rs: sync_enabled_to_opencode, collect_enabled_servers
- opencode_config.rs: 8 unused utility functions
- provider.rs: OpenCodeProviderConfig impl block (4 methods)
These functions were designed for batch operations but McpService uses
per-server sync pattern instead. No functionality affected.
Add mcp/opencode.rs with format conversion between CC Switch and OpenCode:
- stdio ↔ local type conversion
- command+args ↔ command array format
- env ↔ environment field mapping
- sse/http ↔ remote type conversion
Public API:
- sync_enabled_to_opencode: Batch sync all enabled servers
- sync_single_server_to_opencode: Sync individual server
- remove_server_from_opencode: Remove from live config
- import_from_opencode: Import servers from OpenCode config
Also fix test files to include new opencode field in McpApps struct.
All 4 unit tests pass for format conversion.
