Refresh docs to match ultraworkers/claw-code source of truth

Replace the stale Python-first README narrative, old community links, and leftover branded metadata with the current Rust-first repo guidance. Also align funding handles and asset naming so the public docs point at the canonical ultraworkers/claw-code surface.\n\nConstraint: Scope limited to docs/metadata and branding residue; no runtime behavior changes\nRejected: Add a new CI lint in this pass | outside the requested docs-and-config cleanup scope\nConfidence: medium\nScope-risk: narrow\nReversibility: clean\nDirective: Keep README, funding metadata, and community links aligned with ultraworkers/claw-code and the current UltraWorkers Discord invite\nTested: stale-branding grep across markdown/.github; root doc-link existence checks; cargo fmt --all --check; cargo check --workspace; cargo test --workspace\nNot-tested: cargo clippy --workspace --all-targets -- -D warnings | fails on pre-existing runtime lint debt unrelated to these doc changes

 3. Add release-grade binary workflow — repo has a Rust CLI and release intent, but no GitHub Actions path that builds tagged artifacts / checks release packaging before a publish step
 4. Add container-first test/run docs — runtime detects Docker/Podman/container state, but docs do not show a canonical container workflow for `cargo test --workspace`, binary execution, or bind-mounted repo usage
 5. Surface `doctor` / preflight diagnostics in onboarding docs and help — the CLI already has setup-diagnosis commands and branch preflight machinery, but they are not prominent enough in README/USAGE, so new users still ask manual setup questions instead of running a built-in health check first
-6. Add branding/source-of-truth residue checks for docs — after repo migration, old org names can survive in badges, star-history URLs, and copied snippets; docs need a consistency pass or CI lint to catch stale branding automatically
-7. Reconcile README product narrative with current repo reality — top-level docs now say the active workspace is Rust, but later sections still describe the repo as Python-first; users should not have to infer which implementation is canonical
-8. Eliminate warning spam from first-run help/build path — `cargo run -p rusty-claude-cli -- --help` currently prints a wall of compile warnings before the actual help text, which pollutes the first-touch UX and hides the product surface behind unrelated noise
-9. Promote `doctor` from slash-only to top-level CLI entrypoint — users naturally try `claw doctor`, but today it errors and tells them to enter a REPL or resume path first; healthcheck flows should be callable directly from the shell
-10. Make machine-readable status commands actually machine-readable — `status` and `sandbox` accept the global `--output-format json` flag path, but currently still render prose tables, which breaks shell automation and agent-friendly health polling
-11. Unify legacy config/skill namespaces in user-facing output — `skills` currently surfaces mixed project roots like `.codex` and `.claude`, which leaks historical layers into the current product and makes it unclear which config namespace is canonical
-12. Honor JSON output on inventory commands like `skills` and `mcp` — these are exactly the commands agents and shell scripts want to inspect programmatically, but `--output-format json` still yields prose, forcing text scraping where structured inventory should exist
-13. Audit `--output-format` contract across the whole CLI surface — current behavior is inconsistent by subcommand, so agents cannot trust the global flag without command-by-command probing; the format contract itself needs to become deterministic
+6. Automate branding/source-of-truth residue checks in CI — the manual doc pass is done, but badges, Discord invites, copied repo URLs, and org-name drift can regress unless a cheap lint/check keeps README/docs aligned with `ultraworkers/claw-code`
