feat(build): report version as upstream+hash (e.g. 1.17.18+6cdc4d7)

Script.version now reads packages/opencode/package.json for the
upstream semver base and appends +{7-char git hash} via
git rev-parse --short=7 HEAD. OPENCODE_VERSION env var still
overrides when set.

CLI lildax binary uses InstallationVersion instead of hardcoded
'local' for --version flag display.
