Anthony Stirling 5be9a0e1df fix desktop bundles (#6773)
# Description of Changes

Changes
- Use 127.0.0.1 instead of localhost for the local backend. The bundled
backend starts on a random port and binds the IPv4 wildcard, but the
frontend health-checked http://localhost:{port}. On macOS (and some
Linux) localhost resolves to IPv6 ::1 first, so the connection is
refused and every backend-dependent tool shows "backend offline" even
though the backend started fine. Switched getBackendUrl() and the
health-check URL to the 127.0.0.1 loopback literal (already in the Tauri
HTTP capability allowlist, and what the OAuth loopback server already
uses). Client-side tools were unaffected, which matches the reports.
- Fail the desktop build when the bundled JRE is older than the app JAR.
The app JAR is compiled for Java 25, but the bundle could ship an older
runtime/jre (jlink:runtime short-circuits on an existing runtime, and
nothing checked its version), producing UnsupportedClassVersionError at
launch so the backend never starts. Added a jlink:verify task that reads
the jlink release file and fails the build if the bundled JRE major is
below REQUIRED_JAVA (25, kept in sync with build.gradle
modernJavaVersion). It runs after the runtime is staged - including the
short-circuit reuse path that lets a stale JRE slip through.
Cross-platform Node script, no new dependencies.
