Greptile Summary

This PR reorganizes TypeScript config inheritance across the monorepo. The main changes are:

• Adds shared build-only base configs for ESM and CJS packages.
• Moves broad test exclusion out of the general base config.
• Removes repeated package-level exclude lists.
• Moves several fixtures under __tests__/__fixtures__ and updates test imports.

Confidence Score: 4/5

The changed config is mostly safe, but root or package typechecks may now include tests unexpectedly.

• Build configs keep tests excluded.
• Broad package projects can now pull in __tests__ files through the general base config.
• Fixture moves and import updates are aligned with the new paths.

   Root Typecheck Includes Tests

   When the repository or an editor loads package tsconfig.json files that still extend the general base and use broad includes like include: ["."], this change pulls __tests__ files into those projects for the first time. Test files can use test-only globals, fixture imports, or dependencies that are not valid for the package project, so a root tsc --build tsconfig.json or package-level typecheck can fail even though build configs still exclude tests.
