feat(installer): generate OpenCode /<skill> slash commands

Adds .opencode/commands/<canonicalId>.md pointer files for each installed
skill so users can invoke skills directly (e.g. /bmad-quick-dev) instead
of going through the /skills menu.

- platform-codes.yaml: add commands_target_dir field for opencode
- _config-driven.js: installCommandPointers() with skip-if-exists default,
  reserved-name collision guard, YAML-safe description quoting
- _config-driven.js: cleanupCommandPointers() for symmetric uninstall
- test-installation-components.js: extend OpenCode suite with assertions
  covering pointer creation, content, and idempotency

OpenCode-only and opt-in via the new yaml field; other adapters unchanged.
