fix(#251): intercept session-management verbs at top-level parser to bypass credential check

## What Was Broken (ROADMAP #251)

Session-management verbs (list-sessions, load-session, delete-session,
flush-transcript) were falling through to the parser's `_other => Prompt`
catchall at main.rs:~1017. This construed them as `CliAction::Prompt {
prompt: "list-sessions", ... }` which then required credentials via the
Anthropic API path. The result: purely-local session operations emitted
`missing_credentials` errors instead of session-layer envelopes.

## Acceptance Criterion

The fix's essential requirement (stated by gaebal-gajae):
**"These 4 verbs stop falling through to Prompt and emitting `missing_credentials`."**
Not "all 4 are fully implemented to spec" — stubs are acceptable for
delete-session and flush-transcript as long as they route LOCALLY.

## What This Fix Does

Follows the exact pattern from #145 (plugins) and #146 (config/diff):

1. **CliAction enum** (main.rs:~700): Added 4 new variants.
2. **Parser** (main.rs:~945): Added 4 match arms before the `_other => Prompt`
   catchall. Each arm validates the verb's positional args (e.g., load-session
   requires a session-id) and rejects extra arguments.
3. **Dispatcher** (main.rs:~455):
   - list-sessions → dispatches to `runtime::session_control::list_managed_sessions_for()`
   - load-session → dispatches to `runtime::session_control::load_managed_session_for()`
   - delete-session → emits `not_yet_implemented` error (local, not auth)
   - flush-transcript → emits `not_yet_implemented` error (local, not auth)

## Dogfood Verification

Run on clean environment (no credentials):

```bash
$ env -i PATH=$PATH HOME=$HOME claw list-sessions --output-format json
{
  "command": "list-sessions",
  "sessions": [
    {"id": "session-1775777421902-1", ...},
    ...
  ]
}
# ✓ Session-layer envelope, not auth error

$ env -i PATH=$PATH HOME=$HOME claw load-session nonexistent --output-format json
{"error":"session not found: nonexistent", "kind":"session_not_found", ...}
# ✓ Local session_not_found error, not missing_credentials

$ env -i PATH=$PATH HOME=$HOME claw delete-session test-id --output-format json
{"command":"delete-session","error":"not_yet_implemented","kind":"not_yet_implemented","type":"error"}
# ✓ Local not_yet_implemented, not auth error

$ env -i PATH=$PATH HOME=$HOME claw flush-transcript test-id --output-format json
{"command":"flush-transcript","error":"not_yet_implemented","kind":"not_yet_implemented","type":"error"}
# ✓ Local not_yet_implemented, not auth error
```

Regression sanity:

```bash
$ claw plugins --output-format json  # #145 still works
$ claw prompt "hello" --output-format json  # still requires credentials correctly
$ claw list-sessions extra arg --output-format json  # rejects extra args with cli_parse
```

## Regression Tests Added

Inside `removed_login_and_logout_subcommands_error_helpfully` test function:

- `list-sessions` → CliAction::ListSessions (both text and JSON output)
- `load-session <id>` → CliAction::LoadSession with session_reference
- `delete-session <id>` → CliAction::DeleteSession with session_id
- `flush-transcript <id>` → CliAction::FlushTranscript with session_id
- Missing required arg errors (load-session and delete-session without ID)
- Extra args rejection (list-sessions with extra positional args)

All 180 binary tests pass. 466 library tests pass.

## Fix Scope vs. Full Implementation

This fix addresses #251 (dispatch-order bug) and #250's Option A (implement
the surfaces). list-sessions and load-session are fully functional via
existing runtime::session_control helpers. delete-session and flush-transcript
are stubbed with local "not yet implemented" errors to satisfy #251's
acceptance criterion without requiring additional session-store mutations
that can ship independently in a follow-up.

## Template

Exact same pattern as #145 (plugins) and #146 (config/diff): top-level
verb interception → CliAction variant → dispatcher with local operation.

## Related

Closes #251. Addresses #250 Option A for 4 verbs. Does not block #250
Option B (documentation scope guards) which remains valuable.
