fix(exe): restore execute bit on node-gyp shims in @pnpm/exe (#11485)

- Closes #11483.
- `@pnpm/exe@11.x` was packing `dist/node-gyp-bin/node-gyp`, `dist/node-gyp-bin/node-gyp.cmd`, and `dist/node_modules/node-gyp/bin/node-gyp.js` with mode `0644` instead of `0755`. Any install whose lifecycle script invokes `node-gyp rebuild` while pnpm has prepended `dist/node-gyp-bin/` to `PATH` failed with `sh: 1: node-gyp: Permission denied` — most visibly via `pnpm/action-setup@v6`'s standalone path on GitHub Actions runners with system Node < 22.13.
- The regular `pnpm` package's `package.json` already declares `publishConfig.executableFiles` for these three shims, which `pnpm publish` honors by packing matching tar entries with mode `0755` (see `releasing/commands/src/publish/pack.ts:273` and the `bins`-driven mode selection at `pack.ts:360-361`). `@pnpm/exe`'s `package.json` was missing the same field, so the shims it copies from `pnpm/dist/` shipped with `0644`. This PR mirrors the field into `@pnpm/exe`.
- To prevent the two manifests from drifting again, meta-updater is now the single source of truth for the executable-files list and writes it into both `pnpm/package.json` and `pnpm/artifacts/exe/package.json`.
