dx: extend pre-commit hook to check all workspaces

[snowrugar-beep]

Problem Statement

The pre-commit hook (.husky/pre-commit) only runs lint-staged in the Backend directory. It does not run linting or type-checking for Frontend, Analytics, or Contracts (Rust). Issues in these workspaces are only caught in CI.

Evidence

• .husky/pre-commit line 1: cd Backend && npx lint-staged
• No Frontend, Analytics, or Contract checks

Impact

CI fails on Frontend/Analytics/Contracts errors that could be caught locally. Slower feedback loop.

Proposed Solution

Extend pre-commit to:

1. Run cd Frontend && npx lint-staged
2. Run cd analytics && npx lint-staged
3. Run cd contracts && cargo check (only on changed .rs files)

Technical Requirements

• Must still run all checks even if one fails (report all errors)
• Must not slow down commits excessively (< 10 seconds)
• Must skip checks if no relevant files changed

Acceptance Criteria

1. Changing a Frontend file triggers Frontend lint-staged
2. Changing an Analytics file triggers Analytics lint-staged
3. Changing a Rust file triggers cargo check
4. All checks running in parallel
5. Failure in one workspace does not skip other checks

File Inventory

• .husky/pre-commit

Dependencies

None.

Testing Strategy

• Modify file in each workspace and verify pre-commit triggers

Security Considerations

Faster local validation reduces chance of vulnerable code reaching CI.

Definition of Done

• Pre-commit checks all workspaces
• Parallel execution
• All errors reported
