bug(citation-manager): CLI integration test paths break in monorepo root after worktree merge

[WesleyMFrederick]

Summary

4 CLI integration test files reference dist/citation-manager.js from repo root, but the actual build output is at tools/citation-manager/dist/. These tests passed in the worktree context (where dist/ was at root) but fail in the monorepo structure.

Failing Tests (16 failures across 4 files)

• extract-command.test.js — 9 failures
• extract-header.test.js — 4 failures
• extract-links-e2e.test.js — 1 failure
• base-paths-npm-script.test.js — path resolution issue

Root Cause

Worktree branch (typescript-refactor-epic6-extraction-layer-worktree) converted citation-manager.js → citation-manager.ts with build output to dist/. Tests used relative dist/citation-manager.js paths that resolved correctly in the worktree's isolated directory but not from monorepo root.

Fix

Update test file execSync calls to use the correct path relative to monorepo root:

- node dist/citation-manager.js
+ node tools/citation-manager/dist/citation-manager.js

Or use path.resolve(__dirname, ...) for robust resolution.

Context

Introduced during merge of Epic 6/7 worktree branch into typescript-refactor. All 338 other tests pass. See commit 268fdf5.
