feat: add Tier 6 monitoring & CI/CD cartridges (6 cartridges, 59 tools)
Add 6 new Tier 6 cartridges for monitoring and CI/CD: - grafana-mcp (10 tools): dashboard CRUD, datasource queries, alerts, annotations, health - prometheus-mcp (8 tools): instant/range PromQL queries, targets, labels, metadata, series - sentry-mcp (10 tools): issue tracking, events, resolution, releases, DSN, tags, transactions - github-actions-mcp (12 tools): workflows, runs, jobs, artifacts, logs, dispatch, re-run, cancel, secrets, runners, caches - buildkite-mcp (10 tools): pipelines, builds, jobs, logs, artifacts, agents, triggering - circleci-mcp (9 tools): pipelines, workflows, jobs, artifacts, triggering, cancellation, envvars Each cartridge includes: cartridge.json, mod.js, Idris2 ABI (%default total), thread-safe Zig FFI, V-lang adapter, PanLL panels/manifest.json, minter.toml, README.adoc, integration tests, benchmarks. All PMPL-1.0-or-later. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

== Overview
11+
12+
Buildkite CI/CD cartridge for the BoJ server. Provides type-safe access to
13+
the Buildkite REST API v2 for pipeline listing, build management, job inspection,
14+
artifact retrieval, agent listing, build triggering, log retrieval, and cancellation.
