Installing from git gave a package without dist/, so import 'rfb2' failed with ERR_MODULE_NOT_FOUND. npm runs a git dependency's prepare script before packing it, but not prepack, and dist/ was built in prepack.

Change

• package.json: "prepack": "npm run build" becomes "prepare": "npm run build". npm runs prepare on git installs, on npm install / npm ci in a clone, and before npm pack and npm publish, so prepack isn't needed. Installs from the registry don't run it. files is unchanged (dist, src).
• Workflows: dropped the explicit npm run build steps in ci.yml, release-please.yml and release.yml. npm ci now builds dist/, and npm pack --dry-run and npm publish build it again before packing, so the extra step was a third build. Biome already ignores dist/, so lint is unaffected when dist/ exists before it runs.
• README, Development: npm install also builds dist/, and how to install an unreleased branch from git.

Verification

• npm ci in a clean clone runs prepare and writes dist/. npm run check passes (Biome, tsc, 291 unit tests).
• npm pack --dry-run runs prepare and lists dist/ (70 files).
• Install from this branch in an empty directory (npm 11.12.1, Node 26.0.0):

$ npm init -y >/dev/null && npm install github:sidorares/node-rfb2#fix/build-in-prepare

The same install from #master gives LICENSE README.md package.json src and ERR_MODULE_NOT_FOUND.

Closes #35
