Boss-direct plan (no parent spec — this is a P2-roadmap-todo, not a
milestone iter). Option 1 picked from the roadmap fork: auto-parse
.ail internally so `ail check foo.ail` works the same as
`ail check foo.ail.json` (modulo the surface-parse step). Option 2
(hint-only) was a workaround that would have forced LLM-authors to
prepend `ail parse` before every check/build/run.
Architecture: extension dispatch lives in ailang-surface (which
already depends on core); core gains a `load_workspace_with` injection
point so the dispatch reaches transitive imports; surface parse
errors get a new WorkspaceLoadError::SurfaceParse variant so
`workspace_error_to_diagnostic` can route them in --json mode.
Tasks:
1. core::load_workspace_with + WorkspaceLoadError::SurfaceParse
+ .ail-first import resolution
2. surface::load_module + surface::load_workspace
3. crates/ail/src/main.rs rewire (~17 callsites) + 2 e2e tests
4. workspace_error_to_diagnostic SurfaceParse arm + DESIGN.md
§Decision-6 CLI addendum + ct1_check_cli diagnostic test
