Restore Rust formatting compliance for origin/main

Run cargo fmt across the Rust workspace after rebasing onto origin/main so the branch matches rustfmt's current output and the CI formatter gate can pass again. This commit intentionally contains formatter output only and keeps it separate from the README brand refresh.

Constraint: origin/main was failing cargo fmt --all --check
Rejected: Manually format only the initially reported files | cargo fmt --all updated additional workspace files that are part of the formatter gate
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Do not mix behavior edits into formatter-only commits
Tested: cargo fmt --all --check
Tested: cargo test --all
Tested: git diff --check

+## 188K and climbing
+
+Thanks to everyone who starred, tested, reviewed, and pushed the project forward. Claw Code is focused on a straightforward promise: a fast local-first CLI agent runtime with native tools, inspectable behavior, and a Rust workspace that stays close to the metal.
+
+- Native Rust workspace and CLI binary under [`rust/`](./rust)
+- Local-first workflows for prompts, sessions, tooling, and parity validation
+- Open development across the broader UltraWorkers ecosystem
 
 > [!IMPORTANT]
 > Start with [`USAGE.md`](./USAGE.md) for build, auth, CLI, session, and parity-harness workflows. Make `claw doctor` your first health check after building, use [`rust/README.md`](./rust/README.md) for crate-level details, read [`PARITY.md`](./PARITY.md) for the current Rust-port checkpoint, and see [`docs/container.md`](./docs/container.md) for the container-first workflow.

-- Added tool_permission_required worker status and event classification for interactive MCP/tool permission gates.

-- Startup evidence now records tool_permission_prompt_detected and classifies timeout evidence as tool_permission_required.
-- Readiness snapshots now mark tool-permission-gated workers as blocked, not ready/idle.
-- Tests: targeted tool_permission regressions, full runtime test/clippy/fmt pending in Ralph verification loop.

-- Changed help rendering to filter `resume_supported_slash_commands()` through `STUB_COMMANDS` before building the Resume-safe one-liner.
-- Added `stub_commands_absent_from_resume_safe_help` regression coverage so future stub additions cannot leak into the Resume-safe summary.
-- Targeted verification: `cargo test -p rusty-claude-cli stub_commands_absent_from_resume_safe_help -- --nocapture` passed; `cargo test -p rusty-claude-cli parses_direct_cli_actions -- --nocapture` passed.
-- Format/check verification: `cargo fmt --all --check`, `git diff --check`, and `cargo check -p rusty-claude-cli` passed.
-- Broader clippy note: `cargo clippy -p rusty-claude-cli --all-targets -- -D warnings` is blocked by pre-existing `clippy::unnecessary_wraps` failures in `rust/crates/commands/src/lib.rs` (`render_mcp_report_for`, `render_mcp_report_json_for`), outside this diff.
