chore: deny esbuild and fsevents install scripts

npm 11.19 gates dependency lifecycle install scripts behind an
allowScripts allowlist and warns about any package not yet reviewed.
Three were pending: esbuild's postinstall and two copies of fsevents.

None of them is needed. esbuild resolves its platform binary through
optionalDependencies (@esbuild/darwin-*), so install.js is only a
validation/fallback-download step, and both fsevents copies ship a
prebuilt fsevents.node — their install script is just a node-gyp
rebuild fallback. Verified: builds and tests pass with the scripts
skipped.

Denying rather than approving keeps the warning quiet without granting
a standing "run this package's arbitrary install script" permission.
