Changes

Cohort / File(s)	Summary
CI / Workflow `/.github/workflows/headers.yml`	Invocation changed from `pnpm tsx tools/headers.ts` → `pnpm unrun tools/headers.ts`.
Test specs `compat-test/quick-start.spec.ts`, `esm-test/quick-start.spec.ts`, `example/index.spec.ts`	Switched spawned runtime from `tsx` → `unrun` when executing example/test scripts.
Example package `example/package.json`	Scripts `start`, `build:docs`, `build:client` updated from `tsx ...` → `unrun ...`.
Root package `package.json`	`prebuild`/`pretest` scripts updated to use `unrun`; removed `tsx` devDependency; added `unrun@^0.2.17`.
Workspace config `pnpm-workspace.yaml`	Removed `esbuild` from `onlyBuiltDependencies`; removed `tsx` from `minimumReleaseAgeExclude`; added overrides for `lightningcss` and `vite`.
Test expectation `express-zod-api/tests/common-helpers.spec.ts`	Adjusted expected function string formatting from multi-line `() => {\n }` to single-line `() => {}`.

Poem

🐇 I hopped from tsx to unrun today,
Swapped scripts and CI without delay.
A function string trimmed, workspace leaves rearranged,
I nibble a carrot — change well exchanged. 🥕

Does not work well for `unrun`, causes unclear crashes and resolution uncertainty over `ramda` in #3054  ## Summary by CodeRabbit * **Chores** * Updated module import paths and TypeScript compilation configuration for improved build compatibility. * Standardized JSON module import syntax across the codebase. * Enhanced internal API infrastructure with extended interface support for advanced use cases. <sub>✏️ Tip: You can customize this high-level summary in your review settings.</sub>

Copy of #3055 , because the issue in #3054 is not caused by it

Since `tsdown` is going to keep it anyway, it can replace `tsx`

Should go along with #3051 All that will help to get rid of `esbuild` and use faster approach based on Rust.
