Guard unfinished statement parsers in check mode, including nested blocks and exports. Preserve run/parse behavior and the single-file CLI. Verified four unittest regression methods and all five existing CLI test functions locally. Full pytest unavailable in this environment. Document overlap with PR #8 before integration.

RoadC lacked a command for editors and automation to check syntax without executing source. This adds
check/--checkfor one or more UTF-8 files, with optional structured JSON diagnostics.The command never constructs an interpreter or evaluates statements or record defaults. It reports read, lexing, parsing and nesting errors, continues checking later files, and rejects unfinished match/spawn parser branches without hanging. Success means parser acceptance only, not runtime support, type correctness, or C compiler parity.
Integrated with current main after the record-types merge. Consolidates the overlapping PR #9 documentation and nested/export failure coverage into the broader batch interface; #9 can be closed as superseded after merge. Added actual-example batch checks and record-default non-execution regressions. Existing CI configuration is preserved.
