## Problem
`claw config` and `claw diff` are pure-local read-only introspection
commands (config merges .claw.json + .claw/settings.json from disk; diff
shells out to `git diff --cached` + `git diff`). Neither needs a session
context, yet both rejected direct CLI invocation:
$ claw config
error: `claw config` is a slash command. Use `claw --resume SESSION.jsonl /config` ...
$ claw diff
error: `claw diff` is a slash command. ...
This forced clawing operators to spin up a full session just to inspect
static disk state, and broke natural pipelines like
`claw config --output-format json | jq`.
## Root cause
Sibling of #145: `SlashCommand::Config { section }` and
`SlashCommand::Diff` had working renderers (`render_config_report`,
`render_config_json`, `render_diff_report`, `render_diff_json_for`)
exposed for resume sessions, but the top-level CLI parser in
`parse_subcommand()` had no arms for them. Zero-arg `config`/`diff`
hit `parse_single_word_command_alias`'s fallback to
`bare_slash_command_guidance`, producing the misleading guidance.
## Changes
### rust/crates/rusty-claude-cli/src/main.rs
- Added `CliAction::Config { section, output_format }` and
`CliAction::Diff { output_format }` variants.
- Added `"config"` / `"diff"` arms to the top-level parser in
`parse_subcommand()`. `config` accepts an optional section name
(env|hooks|model|plugins) matching SlashCommand::Config semantics.
`diff` takes no positional args. Both reject extra trailing args
with a clear error.
- Added `"config" | "diff" => None` to
`parse_single_word_command_alias` so bare invocations fall through
to the new parser arms instead of the slash-guidance error.
- Added dispatch in run() that calls existing renderers: text mode uses
`render_config_report` / `render_diff_report`; JSON mode uses
`render_config_json` / `render_diff_json_for` with
`serde_json::to_string_pretty`.
- Added 5 regression assertions in parse_args test covering:
parse_args(["config"]), parse_args(["config", "env"]),
parse_args(["config", "--output-format", "json"]),
parse_args(["diff"]), parse_args(["diff", "--output-format", "json"]).
### ROADMAP.md
Added Pinpoint #146 documenting the gap, verification, root cause,
fix shape, and acceptance. Explicitly notes which other slash commands
(`hooks`, `usage`, `context`, etc.) are NOT candidates because they
are session-state-modifying.

## Tests
- rusty-claude-cli bin: 177 tests pass (5 new assertions in parse_args)
- Full workspace green except pre-existing resume_latest flake (unrelated)
## Not changed
`hooks`, `usage`, `context`, `tasks`, `theme`, `voice`, `rename`,
`copy`, `color`, `effort`, `branch`, `rewind`, `ide`, `tag`,
`output-style`, `add-dir` — all session-mutating or interactive-only;
correctly remain slash-only.
Closes ROADMAP #146.
