Add inject_limit_offset (tht/execute/limit.py) — pure subquery wrapper that applies LIMIT/OFFSET non-destructively without clobbering user-supplied LIMITs. Wire offset param into do_run (pre-processing when offset>0) and add --offset / --json flags to preview_cmd; JSON mode emits pristine stdout with columns, rows, execution_ms, truncated, limit, offset. 5 new tests (4 unit + 1 JSON-purity), 219/219 total passing (no regressions).
