fix(#122b): claw doctor warns when cwd is broad path (home/root)

## What Was Broken

`claw doctor` reported "Status: ok" when run from ~/ or /, but `claw
prompt` in the same directory would error out with:

    error: claw is running from a very broad directory (/Users/yeongyu).
    The agent can read and search everything under this path.

Diagnostic deception: doctor said green, prompt said red. User runs
doctor to check their setup, sees all green, runs prompt, gets blocked.
Trust in doctor erodes.

This is the exact pattern captured in the 'Diagnostic Commands Must Be
At Least As Strict As Runtime Commands' principle recorded in ROADMAP.md
at cycle #57.

## Root Cause

Two code paths perform the broad-cwd check:
- CliAction::Prompt handler → `enforce_broad_cwd_policy()` (errors out)
- CliAction::Repl handler → same function

But render_doctor_report() never called detect_broad_cwd(). The workspace
health check only looked at whether cwd was inside a git project, not
whether cwd was a dangerously broad path.

## What This Fix Does

Extend `check_workspace_health()` to also probe `detect_broad_cwd()`:

    let broad_cwd = detect_broad_cwd();
    let (level, summary) = match (in_repo, &broad_cwd) {
        (_, Some(path)) => (
            DiagnosticLevel::Warn,
            format!(
                "current directory is a broad path ({}); Prompt/REPL will \
                 refuse to run here without --allow-broad-cwd",
                path.display()
            ),
        ),
        (true, None) => (DiagnosticLevel::Ok, "project root detected"),
        (false, None) => (DiagnosticLevel::Warn, "not inside a git project"),
    };

The check now warns about BOTH failure modes with clear messaging about
what Prompt/REPL will do.

## Dogfood Verification

Before fix:
    $ cd ~ && claw doctor
    Workspace
      Status           warn
      Summary          current directory is not inside a git project
    [all green otherwise]

    $ echo | claw prompt "test"
    error: claw is running from a very broad directory (/Users/yeongyu)...

After fix:
    $ cd ~ && claw doctor
    Workspace
      Status           warn
      Summary          current directory is a broad path (/Users/yeongyu);
                       Prompt/REPL will refuse to run here without
                       --allow-broad-cwd

    $ cd / && claw doctor
    Workspace
      Status           warn
      Summary          current directory is a broad path (/); ...

Non-regression:
    $ cd /tmp/my-project && claw doctor
    Workspace
      Status           warn
      Summary          current directory is not inside a git project
    (unchanged)

    $ cd /path/to/real/git/project && claw doctor
    Workspace
      Status           ok
      Summary          project root detected on branch main
    (unchanged)

## Regression Tests Added

- `workspace_check_in_project_dir_reports_ok` — non-broad + in-project = OK
- `workspace_check_outside_project_reports_warn` — non-broad + not-in-project = Warn with 'not inside git project' summary
- 181 binary tests pass (was 179, added 2)

## Related

- Principle: 'Diagnostic Commands Must Be At Least As Strict As Runtime
  Commands' (ROADMAP.md cycle #57)
- Companion to #122 (stale-base preflight in doctor)
- Sibling: next step is probably a full runtime-vs-doctor audit for
  other asymmetries (auth, sandbox, plugins, hooks)

-
-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
+Claw Code is the public Rust implementation of the `claw` CLI agent harness.
+The canonical implementation lives in [`rust/`](./rust), and the current source of truth for this repository is **ultraworkers/claw-code**.
 
 > [!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.
