What: - delete oracle package and plugin exports - remove oracle from tool update and skill sync pipelines - remove oracle mentions from README Why: - oracle is no longer part of the bundled toolchain - keep package/update surface aligned with active bundled plugins only Tests: - go test ./... (pass) - nix flake check --no-build (pass)
