fix(intelligence): fix Process resource leak in RepositoryIdentity.runGit()

Process does not implement AutoCloseable in Java 25, so try-with-resources
is not applicable. Use try-finally with proc.destroy() to ensure OS process
handles are always released, resolving SonarQube C-Reliability finding.

Closes RAN-156
