BogdanandGitHub d427a4b2bb perf(cli): enable Node module compile cache (#2092)
* perf(cli): enable Node module compile cache

Warm CLI invocations spend substantial time compiling the bundled ESM entrypoint. Enable Node's optional on-disk compile cache only in the process that imports the bundle, while preserving early Node 22 compatibility and making cache failures non-fatal.

Add deterministic launcher coverage, packaging checks, and a reproducible benchmark procedure so the startup benefit can be measured without flaky CI thresholds.

* fix(ci): isolate minimum Node launcher check

The full validation suite depends on knip and oxc-parser behavior unavailable in Node 22.0.0. Keep full CI on the active Node 22 line and exercise the declared runtime floor in a dedicated build-and-launch job.

* fix(benchmark): harden startup measurements

Keep environment setup outside the timed process window, document the API's Node 22.8 floor, and preserve completed benchmark results when git metadata is unavailable.

* test(cli): verify compile cache disable behavior

Pair NODE_DISABLE_COMPILE_CACHE with a temporary cache directory and assert that supported Node releases leave it empty while preserving normal launcher output.
