YeonGyu-Kim 01dca90e95 fix: #167 — show-command and show-tool now accept --output-format flag; CLI parity with session-lifecycle family
Closes the inspect-capability parity gap: show-command and show-tool were
the only discovery/inspection CLI commands lacking --output-format support,
making them outliers in the ecosystem that already had unified JSON
contracts across list-sessions, load-session, delete-session, and
flush-transcript (#160/#165/#166).

Concrete additions:

- show-command: --output-format {text,json}
- show-tool: --output-format {text,json}

JSON envelope shape (found case):
  {name, found: true, source_hint, responsibility}

JSON envelope shape (not-found case):
  {name, found: false, error: {kind:'command_not_found'|'tool_not_found',
                               message, retryable: false}}

Exit codes:
  0 = success
  1 = not found

Backward compatibility:
  - Default (no --output-format) is 'text' (unchanged)
  - Text output byte-identical to pre-#167 (three newline-separated lines)

Tests (10 new, test_show_command_tool_output_format.py):
  - TestShowCommandOutputFormat (5): found + not-found in JSON; text mode
    backward compat; text is default
  - TestShowToolOutputFormat (3): found + not-found in JSON; text mode
    backward compat
  - TestShowCommandToolFormatParity (2): both accept same flag choices;
    consistent JSON envelope shape

Full suite: 114 → 124 passing, zero regression.

Closes ROADMAP #167.

Why this matters:
  Before: Claws calling show-command/show-tool had to parse human-readable
  prose output via regex, with no structured error signal.
  After: Same envelope contract as load-session and friends: JSON-first,
  typed errors, machine-parseable.

Related clusters:
  - Session-lifecycle CLI parity family (#160, #165, #166, #167)
  - Machine-readable error contracts (same vein as #162 atomicity + #164
    cancellation state-safety: structured boundaries for orchestration)

"""Tests for --output-format flag on show-command and show-tool (ROADMAP #167).
Verifies parity with session-lifecycle CLI family (#160/#165/#166):
- show-command and show-tool now accept --output-format {text,json}
- Found case returns success with JSON envelope: {name, found: true, source_hint, responsibility}
- Not-found case returns typed error envelope: {name, found: false, error: {kind, message, retryable}}
- Legacy text output (default) unchanged for backward compat
- Exit code 0 on success, 1 on not-found (matching load-session contract)
