* fix(windows): keep windows-process-tree gyp paths absolute under pnpm
Hourly Windows builds have failed since #16598 at
`build-windows-process-tree-relay-addon`: `require('node-addon-api').targets`
is cwd-relative, so node-gyp evaluates it from the pnpm store realpath and
then loads it from the `node_modules` symlink. That resolves
`node_addon_api.gyp` outside the repo.
Use `require.resolve` for an absolute path, matching the node-pty patch.
* i18n: keep ja skill-filter labels on the catalog's Agent brand
#16682 merged with a failing localization catalog: ja used エージェント
in three new skill-filter strings, and repair-locale-catalog rewrites
those to Agent. Match the rest of ja.json so static analysis can pass.
