refactor: extract check command into its own module

[fengmk2]

Move the check command's orchestration logic, output analysis types,
and parsing functions from cli.rs into a dedicated check/ directory,
following the same pattern as exec/.

cli.rs: 1,778 → 1,314 lines
check/mod.rs: execute_check() orchestration (247 lines)
check/analysis.rs: types, parsers, formatters (255 lines)

Note

Medium Risk
Primarily a refactor, but it changes how vp check is dispatched and how fmt/lint output is captured/parsed, which could affect exit codes or CI output stability.

Overview
Refactors the vp check implementation by extracting its orchestration and output-parsing logic from cli.rs into a new check/ module (check/mod.rs + check/analysis.rs), keeping the same fmt→lint flow and --fix re-format pass.

Updates cli.rs visibility to reuse resolve_universal_vite_config and resolve_and_capture_output, and switches the Check subcommand handler to delegate to crate::check::execute_check; related LintMessageKind tests move with the extraction. Documentation in rfcs/check-command.md is updated to reflect the new module layout and cache-input helper naming.
