feat: add full OpenAPI spec parity to MCP server

[miguelangaranocurrents]

This commit implements all missing API endpoints from the Currents REST API OpenAPI specification (v1.0.0) to achieve full parity between the OpenAPI spec and the MCP server implementation.

Changes:

1. Actions API (7 new tools) - OpenAPI paths /actions/*

   • currents-list-actions: List all actions with filtering (GET /actions)
   • currents-create-action: Create new test rules (POST /actions)
   • currents-get-action: Get single action details (GET /actions/{actionId})
   • currents-update-action: Modify existing actions (PUT /actions/{actionId})
   • currents-delete-action: Archive actions (DELETE /actions/{actionId})
   • currents-enable-action: Activate disabled actions (PUT /actions/{actionId}/enable)
   • currents-disable-action: Deactivate actions (PUT /actions/{actionId}/disable)

2. Projects API (2 new tools) - OpenAPI paths /projects/*

   • currents-get-project: Get single project by ID (GET /projects/{projectId})
   • currents-get-project-insights: Get aggregated metrics with time-series data (GET /projects/{projectId}/insights)

3. Runs API (6 new tools) - OpenAPI paths /runs/*

   • currents-delete-run: Permanently remove runs (DELETE /runs/{runId})
   • currents-update-run: Modify run metadata and tags (PUT /runs/{runId})
   • currents-cancel-run: Stop in-progress runs (PUT /runs/{runId}/cancel)
   • currents-reset-run: Reset failed specs for re-execution (PUT /runs/{runId}/reset)
   • currents-find-run: Lookup runs by CI build ID (POST /runs/find)
   • currents-cancel-ci-github: Cancel GitHub Actions workflows (POST /runs/cancel-ci/github)

4. Request Library Enhancements

   • Added putApi() method for PUT requests with optional body
   • Added deleteApi() method for DELETE requests
   • Maintains consistent error handling and logging patterns

All implementations:

• Follow OpenAPI spec exactly for endpoints, parameters, and schemas
• Use zod for runtime type validation matching OpenAPI schemas
• Include comprehensive JSDoc descriptions from OpenAPI spec
• Support all query parameters, filters, and request bodies per spec
• Maintain backward compatibility with existing 8 tools
• Pass all existing tests (16 tests, 2 test suites)

OpenAPI Spec Reference:

• Base URL: https://api.currents.dev/v1
• Spec URL: https://api.currents.dev/v1/docs/openapi.json
• Version: 1.0.0

Previous Coverage: 8/18 API endpoint groups (44%)
New Coverage: 18/18 API endpoint groups (100%)
