typecheck.rs, schema/parser.rs, and query/parser.rs each had
~1000-line inline `mod tests` blocks that overshadowed the production
code in the file. Move each to a sibling `*_tests.rs` using
`#[path = "..."] mod tests;`.
- typecheck.rs: 2865 → 1708 lines; typecheck_tests.rs: 1156 lines
- schema/parser.rs: 1950 → 994 lines; parser_tests.rs: 955 lines
- query/parser.rs: 1737 → 803 lines; parser_tests.rs: 933 lines
No visibility change — the sibling module still has `use super::*`
access to crate-privates. No semantic edits beyond de-indenting by
4 spaces (mechanical). All 229 compiler tests green, identical
count to before.

Allow mutation queries to contain multiple sequential statements that
execute atomically within a single transactional run. This enables
patterns like inserting a node and its edges in one query:
query add_and_link($name: String, $age: I32, $friend: String) {
insert Person { name: $name, age: $age }
insert Knows { from: $name, to: $friend }
}
Changes span the full compiler-to-execution pipeline:
- Grammar: mutation_body = { mutation_stmt+ }
- AST: QueryDecl.mutations: Vec<Mutation>
- IR: MutationIR.ops: Vec<MutationOpIR>
- Execution: loop over ops, accumulate affected counts
Cross-statement visibility works because each statement's commit_updates
advances the manifest state, so subsequent statements see prior writes.
Atomicity comes from the existing run mechanism (begin_run/publish_run).
