src/syntax.rs had grown to about 4,900 lines: name validation, every AST type, and two impl blocks of about 1,800 and 1,600 lines, all next to 15 child modules. That made the parser hard to navigate and changes to it hard to review (VIBE-106).

This PR only moves code; behavior doesn't change. Each commit moves one concern into a child module, following the impl Parsing / impl Parser split that modules.rs and suffixes.rs already use. syntax.rs is down to 386 lines and keeps the declarations, re-exports, entry points and the task plumbing.

Besides the moved lines, the diff only has:

• the new mod and use lines and the impl headers
• pub(super) on the items and the two depth fields that are now used from another module

git diff --color-moved=plain marks every other line as moved.
