Publish canjv to Homebrew after PyPI releases #225

Is your feature request related to a problem? Please describe.

The published codeanalyzer-java wheel already provides canjv and a bundled JVM through jdk4py>=21,<22, but Java releases do not update the shared Homebrew tap.

Add a Homebrew job after successful PyPI publication, following codeanalyzer-python's version-pinned uvx launcher pattern. Generate Formula/codeanalyzer-java.rb from the published universal wheel URL and SHA256, and push it to codellm-devkit/homebrew-tap. Document installation and the first-use download of the package and JVM.

Acceptance criteria:

• Successful PyPI publication updates the tap for the same version; failed publication does not.
• Tap failures can be retried, and unchanged formulas are a successful no-op.
• brew install codellm-devkit/homebrew-tap/codeanalyzer-java exposes canjv without requiring system Java.
• Workflow and formula validation pass.

Ship the automation with the next release; do not cut a new Java release for this change. Backfill the tap now with the existing PyPI release 3.0.2.

Deployment prerequisite: HOMEBREW_TAP_TOKEN must be available to codeanalyzer-java with write access to the shared tap. No repository-level secret with this name was listed during verification; an organization secret may supply it.
