Fixes https://github.com/xtermjs/xterm.js/issues/5896 TypeScript path mappings for common/*, browser/*, and headless/* were not rewritten in emitted JavaScript, which forced webpack resolve aliases and NODE_PATH workarounds so runtime could resolve modules. That added build complexity and broke tooling such as ESLint import/no-cycle. Changes: - Convert ~750 imports across src/, addons/, and test/ to relative paths - Remove common/browser/headless paths and src catch-all mappings from tsconfigs (keep @xterm/addon-* demo and addon typings paths) - Remove webpack resolve.alias for common, browser, headless, and vs - Drop NODE_PATH from unit tests, benchmarks, and VS Code launch config - Fix addon-image IIPImageStorage to import ./Types after removing catch-all * Verified: npm run build, esbuild, package, package-headless Co-authored-by: Cursor <cursoragent@cursor.com>
