Barrett Ruth b90ac67826 feat(config): add language version selection with setup-time validation ... Problem: users cannot choose which C++ standard (e.g. C++17 vs C++20 vs C++23) to submit with — the plugin hardcodes a single platform ID per language with no discoverability or override mechanism. Solution: add `LANGUAGE_VERSIONS` and `DEFAULT_VERSIONS` tables in `constants.lua` as the single source of truth. `config.lua` gains `version` and `submit_id` fields on `CpLanguage`/`CpPlatformOverrides`, validated at setup time. `submit.lua` resolves the effective config to a platform ID (priority: `submit_id` > `version` > default). Helpdocs document the new `*cp-submit-language*` section with per-platform available versions and the `submit_id` escape hatch. Tests cover `LANGUAGE_IDS` completeness and `get_language_id` lookups.		2026-03-06 18:04:04 -05:00
