feat!: JFrog Platform MCP authenticates via OAuth (#31)

The Platform MCP now uses OpenCode OAuth auto-detection via JFROG_PLATFORM_URL and no longer injects a Bearer token (code merged in #29). This empty commit triggers the release.

BREAKING CHANGE: JFROG_URL/JFROG_ACCESS_TOKEN are no longer used for the JFrog Platform MCP; authentication is OAuth via JFROG_PLATFORM_URL.
