This release updates the TypeScript configuration that Keel generates for new and existing projects.

Updated TypeScript config for new and existing projects

New projects now get moduleResolution: "bundler" and module: "ES2022" in their tsconfig.json. The old moduleResolution: "node" setting is deprecated in TypeScript 6 and stops working in TypeScript 7, so Keel no longer uses it.

Existing projects are migrated automatically the next time you run keel run or keel generate:

• moduleResolution: "node" (and the "node10" alias) becomes "bundler".
• module is set to "ES2022" if it is missing or set to an incompatible value such as "CommonJS". Compatible values like "ESNext" are left as they are.
• The ignoreDeprecations entry is removed because it is no longer needed.

The generated include now points at the single file the type checker needs (.build/vitest-matchers.d.ts) instead of the broad .build/**/*.ts glob. The broad glob could pull stale generated files into the type check during keel run and break the functions build, so this makes local builds more reliable.
