Commit Message

feat: 0.7.0 - devcontainer, soak harness, aarch64 releases, deps, ephemeral connections

Added
- Compose-based Dev Container (Rust app + mariadb, optional Prometheus + Grafana
  observability profile); devcontainer-aware 'just test' honoring a pre-set DSN.
- Self-contained local soak/leak harness (scripts/benchmark/) driven by
  mariadb_loadtest.py, sampling the exporter's own mariadb_exporter_process_* metrics.
- aarch64 release artifacts (linux musl + macOS) in the release workflow.
- Developer tooling (install-mariadb-client, monitor-exporter, pre-commit-hook,
  dev-up/dev-ssh/metrics-dev, mise.toml) and docs (CONTRIBUTING, copilot-instructions).

Changed
- Replace the dormant per-database pool cache in collectors::util with an ephemeral
  open_db_connection (bare connection, closed on drop, never cached); locked by
  tests/collectors/connection.rs.

Dependencies
- Update to latest, incl. sqlx 0.8->0.9 (AssertSqlSafe for internal queries),
  OpenTelemetry 0.31->0.32, tracing-opentelemetry 0.32->0.33, tower-http 0.6->0.7,
  sysinfo 0.38->0.39; bump GitHub Actions (checkout v7, cache v6, codecov v7).

Fixed
- Grafana: normalize collapsed-row child gridPos.y to absolute so panels render
  aligned on expand (Exporter Self-Monitoring, User Statistics, and 7 others).
- metrics-dev: select the correct devcontainer project and offset observability host
  ports to 3001/9091 so it coexists with another exporter's stack.
