feat: read pnpm version from devEngines.packageManager (#211)

* feat: read pnpm version from devEngines.packageManager field

When no version is specified in the action config or the packageManager
field of package.json, fall back to devEngines.packageManager.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* feat: skip self-update for devEngines.packageManager and add CI tests

pnpm auto-switches to the right version when devEngines.packageManager
is set, so self-update is unnecessary. This also enables range support
(e.g. ">=9.15.0") which self-update doesn't handle.
