feat(mcp): add tool presets and audit commands

- Introduce reference MCP presets with installation/audit helpers and remove legacy connector lists.
- Add CLI `owlen tools` commands to install presets or audit configuration, with optional pruning.
- Extend the TUI :tools command to support listing presets, installing them, and auditing current configuration.
- Document the preset workflow and provide regression tests for preset application.

 - Update `config.toml` with the reference bundle (see `docs/configuration.md`).
 - Use `owlen tools audit` to remove or disable any legacy MCP servers that do not meet the naming constraints.
 - Track connector-specific onboarding (API keys, OAuth scopes) in team documentation so new contributors can reproduce the setup quickly.

+## Preset Workflow
+
+Run these helpers after updating Owlen to align your MCP configuration with the reference bundles:
+
+```bash
+# Install the baseline connectors
+owlen tools install standard
+
+# Extend with retrieval and automation
+owlen tools install extended
+
+# Switch to the full SaaS bundle (remove anything not in the preset)
+owlen tools install full --prune
+
+# Review current configuration against the full preset
+owlen tools audit full
+```
+
+Within the TUI the same presets are available via commands such as `:tools install standard --prune` and `:tools audit full`.
