Configure JSCPD duplicate code detection in CI

[google-labs-jules]

Configured root CI gates to run duplicate code detection checks using jscpd. This includes adding the necessary dependency, configuring a script for both local and CI use, and ensuring generated reports are properly ignored.

Fixes #3194

[ARCHITECTURE] Review

No HIGH / Blocking issues found.

The diff introduces JSCPD duplicate code detection into CI, adds the necessary dependency, configures the script, and ensures generated reports are ignored. All changes are configuration or script additions, with no evidence of broken references, syntax errors, or workflow misconfigurations.

Key checks:

• The new audit:duplication script is correctly added to package.json and referenced in both the CI workflow and the local aggregate script.
• The jscpd dependency is added to devDependencies.
• The .jscpd.json ignore list is expanded to include report/** and artifacts/**, which are also ignored in .gitignore.
• The new workflow step is syntactically correct and does not reference any missing outputs, secrets, or jobs.

No evidence of:

• Broken dependency or script references.
• YAML syntax errors.
• Unintended exposure of secrets or outputs.
• Design system/layout violations (not applicable to this diff).
• Security regressions.

All changes are strictly additive and scoped to CI and configuration.

[PERFORMANCE] Review

Review Summary:

This diff introduces JSCPD duplicate code detection into CI, adds the jscpd dependency, configures a new audit script, and ensures generated reports are ignored. The changes are limited to CI workflow, .gitignore, .jscpd.json, and package.json. As a PERFORMANCE ENGINEER, I am reviewing for expensive computations, redundant re-renders, large bundle impacts, and inefficient data structures.

HIGH Severity/Blocking Issues:

After careful review, I find no blocking issues in this diff:

• The addition of jscpd as a dev dependency ("jscpd": "^5.0.11") does not impact production bundle size or runtime performance.
• The new script "audit:duplication": "jscpd ." is only run in CI and local audits, not in production or app runtime.
• The CI workflow step is correctly added and does not reference any missing outputs, secrets, or jobs.
• .gitignore and .jscpd.json changes are correct and prevent report artifacts from polluting the repo.
• No expensive computations, redundant re-renders, or inefficient data structures are introduced in app code.
• No design system violations, as no UI/layout code is touched.

All changes are scoped to build, audit, and CI configuration. No runtime or app-layer code is affected.

Questions/Nitpicks (Non-blocking):

• The "audit:duplication": "jscpd ." command will scan the entire repo. If the repo contains very large directories or files not excluded in .jscpd.json, this could increase CI time. However, the exclusion list appears comprehensive and includes report/**, artifacts/**, and test files.
• The "report/" directory is added to .gitignore and .jscpd.json excludes it, preventing recursive scanning and pollution.
• No evidence of redundant or expensive computation in CI steps; the new step is isolated and non-blocking.

No missing types, bugs, or anti-patterns are present in the diff.

ANTI-AI-SLOP

None. Adding jscpd to CI is a standard code-quality step.

FINDINGS

The PR adds `jscpd` for duplicate code detection as requested. However, it is failing `Lint & Type Check (boomtick-mcp)` due to `AssertionError: expected [Function] to throw error including 'Failed to create session: PR not found'` which needs to be resolved before merging.

Audit Checklist

For EVERY changed file, verify against these standards. Mark as - [x] when verified.

• Dead abstractions: No new class, context, or hook that a simpler primitive handles.
• Unnecessary indirection: No layer of wrapping where a direct function call suffices.
• Responsibility creep: Component does not take on state/logic belonging in parent/hook.
• Import bloat: No unnecessary import React from 'react' (React 17+).
• Token compliance: Uses established design tokens (no raw Tailwind values or inline styles).
• Audit ratio: If > 100 lines added, identified at least 10 lines to refactor/remove.

CI Log Triage

• Failed Checks:
  Lint & Type Check (boomtick-mcp)
• Detected Errors:
  AssertionError: expected [Function] to throw error including 'Failed to create session: PR not found' but got 'td-cli command failed (gh view 999): ...' in src/tools/jules/create-session.test.ts and src/tools/jules/get-pr.test.ts.
• Root Cause Analysis:
  The tests in boomtick-mcp are failing because the expected error messages and session formats do not match the updated CLI behavior or required formatting (e.g., missing name: "sessions/<id>" prefix for Jules sessions).
• Remediation Steps:
  Update the mock assertions in the failing tests to expect the updated CLI error messages and ensure that mock session objects properly include the name field prefixed with sessions/.
