* fix(perf): share jiti module cache across extension loads (#2108)
Each extension was creating a new jiti instance with moduleCache: false,
causing shared dependencies to be recompiled for every extension. Use a
shared singleton with moduleCache: true so shared modules are compiled once.
Export resetExtensionLoaderCache() for test teardown and explicit reload.

* fix: correct loader path in extension-load-perf test (4 → 3 levels up)
The test file is at src/tests/ (2 levels deep from repo root), so
fileURLToPath(import.meta.url) + 3x'..' reaches the repo root.
Using 4 levels exits the repo into the GitHub Actions workspace parent,
causing ERR_MODULE_NOT_FOUND for loader.js in dist/.

* fix: use process.cwd() for loader path in perf test (source/compiled portability)
import.meta.url resolves to different depths in source (src/tests/) vs compiled
(dist-test/src/tests/), so relative '../' navigation produces the wrong path in
the build phase. process.cwd() is always the repo root in CI regardless of
where the test file is compiled to.
