Updates the terminology and configuration for the intermediate policy tier
from "Project" to "Workspace" to better align with the Gemini CLI ecosystem.
Key changes:
- Renamed `PROJECT_POLICY_TIER` to `WORKSPACE_POLICY_TIER`.
- Renamed `getProjectPoliciesDir` to `getWorkspacePoliciesDir`.
- Updated integrity scope from `project` to `workspace`.
- Updated UI dialogs and documentation.
- Renamed related test files.
Updates the policy engine to prioritize User policies over Project-specific policies.
This change is a security measure to ensure that users maintain control over their
environment and are not inadvertently compromised by policies defined in a cloned
repository.
Key Changes:
- Swapped Tier 2 (now Project) and Tier 3 (now User).
- Updated documentation to reflect the new hierarchy.
- Updated all built-in policy TOML files with correct tier information.
- Adjusted all tests and integration test expectations to match new priority values.
Adds the 'Project' tier (Base 3) to the policy engine documentation.
Updates the priority hierarchy, location table, and formula examples
to reflect the new Project -> User precedence.
