Subject: [PATCH] fix(version): add build_date and executable_path to version
 JSON output

`claw version --output-format json` was missing build_date and
executable_path, making it impossible to identify which binary is
running or correlate it with a specific build/commit.

Fix: version_json_value() now includes:
- build_date: compile-time BUILD_DATE env (already in text output)
- executable_path: std::env::current_exe() at runtime

Test: version_emits_json_when_requested extended to assert both fields
are strings in the JSON envelope.

Pinpoint: ROADMAP #507
