fix(config): emit section and section_value in JSON output for config subcommands

`claw config model --output-format json` and all other section subcommands
(`env`, `hooks`, `plugins`) returned identical output with no section field
— the section arg was parsed but discarded (_section parameter).

Fix: render_config_json now:
- Passes section through to handler
- Looks up the section value via runtime_config.get(), converting the
  internal JsonValue to serde_json::Value via render()+parse
- Emits `section` (string) and `section_value` (JSON value or null)
  in the response envelope
- Returns ok:false + error for unsupported section tokens

Test: config_section_json_emits_section_and_value asserts:
- No section field when no section arg
- section + section_value fields present for all known sections
- ok:false + error for unknown section
