sync-versions: stop stamping vendored-upstream workspaces with the Cat 1 branch version. brush is a vendored upstream (reubeno/brush) whose 12 crates carry their own upstream versions with internal ^ requirements (brush needs brush-parser ^0.4.0, brush-core 0.5.0, ...); rewriting them all to 0.3.1 broke the build. The old git-untracked heuristic stopped catching brush once it was vendored (committed). Add a provenance-based .vendored-upstream opt-out marker (covers the whole class, not just brush) read by should_exclude. build-redbear.sh: - versioning: BUILD_REDBEAR_VERSION (starts 1.0), --version flag, startup banner, auto-bumped by pre-commit hook (bump-build-version.sh) - colored output (TTY + NO_COLOR aware) - prefix rebuild: stop reporting 'rebuilt successfully' on a make no-op; remove derived prefix markers so a stale relibc actually re-cooks into the sysroot; skip the rebuild when only kernel/base (which don't feed the prefix) advanced - record fork source-fingerprints only after a successful build (not before make live), so a failed build no longer marks forks as built Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
