YeonGyu-Kim 9dd7e79eb2 fix(#130e-B): route plugins/prompt --help to dedicated help topics
## What Was Broken (ROADMAP #130e Category B)

Two remaining surface-level help outliers after #130e-A:

    $ claw plugins --help
    Unknown /plugins action '--help'. Use list, install, enable, disable, uninstall, or update.

    $ claw prompt --help
    claw v0.1.0  (top-level help — wrong help topic)

`plugins` treated `--help` as an invalid subaction name. `prompt`
was explicitly listed in the early `wants_help` interception with
commit/pr/issue, which routed to top-level help instead of
prompt-specific help.

## Root Cause (Traced)

1. **plugins**: `parse_local_help_action()` didn't have a "plugins"
   arm, so `["plugins", "--help"]` returned None and continued into
   the `"plugins"` parser arm (main.rs:1031), which treated `--help`
   as the `action` argument. Runtime layer then rejected it as
   "Unknown action".

2. **prompt**: At main.rs:~800, there was an early interception for
   `--help` following certain subcommands (prompt, commit, pr, issue)
   that forced `wants_help = true`, routing to generic top-level help
   instead of letting parse_local_help_action produce a prompt-specific
   topic.

## What This Fix Does

Same pattern as #130c/#130d/#130e-A:

1. **LocalHelpTopic enum extended** with Plugins, Prompt variants
2. **parse_local_help_action() extended** to map both new cases
3. **Help topic renderers added** with accurate usage info
4. **Early prompt-interception removed** — prompt now falls through to
   parse_local_help_action like other subcommands. commit/pr/issue
   (which aren't actual subcommands yet) remain in the early list.

## Dogfood Verification

Before fix:
    $ claw plugins --help
    Unknown /plugins action '--help'. Use list, install, enable, ...

    $ claw prompt --help
    claw v0.1.0
    (top-level help, not prompt-specific)

After fix:
    $ claw plugins --help
    Plugins
      Usage            claw plugins [list|install|enable|disable|uninstall|update] [<target>]
      Purpose          manage bundled and user plugins from the CLI surface
      ...

    $ claw prompt --help
    Prompt
      Usage            claw prompt <prompt-text>
      Purpose          run a single-turn, non-interactive prompt and exit
      Flags            --model · --allowedTools · --output-format · --compact
      ...

## Non-Regression Verification

- `claw plugins` (no args) → still displays plugin inventory 
- `claw plugins list` → still works correctly 
- `claw prompt "text"` → still requires credentials, runs prompt 
- All 180 binary tests pass 
- All 466 library tests pass 

## Regression Tests Added (4+ assertions)

- `plugins --help` → HelpTopic(Plugins)
- `prompt --help` → HelpTopic(Prompt)
- Short forms `plugins -h` / `prompt -h` both work
- `prompt "hello world"` still routes to Prompt action with correct text

## HELP-PARITY SWEEP COMPLETE

All 22 top-level subcommands now emit proper help topics:

| Command | Status |
|---|---|
| help --help |  #130e-A |
| version --help |  pre-existing |
| status --help |  pre-existing |
| sandbox --help |  pre-existing |
| doctor --help |  pre-existing |
| acp --help |  pre-existing |
| init --help |  pre-existing |
| state --help |  pre-existing |
| export --help |  pre-existing |
| diff --help |  #130c |
| config --help |  #130d |
| mcp --help |  pre-existing |
| agents --help |  pre-existing |
| plugins --help |  #130e-B (this commit) |
| skills --help |  pre-existing |
| submit --help |  #130e-A |
| prompt --help |  #130e-B (this commit) |
| resume --help |  #130e-A |
| system-prompt --help |  pre-existing |
| dump-manifests --help |  pre-existing |
| bootstrap-plan --help |  pre-existing |

Zero outliers. Contract universally enforced.
