feat(types): IVec2 + Rect 2D value types (#1)
Phase 1 of the fuller type-system proposal: two by-value spatial types
that lower to packed integers (no heap, copy like scalars).

- IVec2 — integer 2D vector, a pair of int packed into one i64, for tile
  and grid coordinates: make/zero/x/y/add/sub/scale/dot, the grid distance
  manhattan, equal, and to_vector (widen into the fixed-point Vector).
- Rect — axis-aligned rectangle, four Q16.16 fixed components packed into
  one i128, for HUD boxes and hitboxes: make/x/y/w/h, the derived
  right/bottom/center, and the contains (point) / intersects (overlap) tests.

Both are exact and deterministic, bit-identical on every platform. Vector
and Color already cover phase 1's other 2D primitives.

Wired end to end: emit_core llty (IVec2->i64, Rect->i128), emit_call
dispatch, the FRAGS list + reseeded seed, a selfhost test (types2d),
per-symbol docs + type pages + inventory, and the vocabulary/editor sync
(header, JetBrains, TextMate, LSP).

Changesets

A changeset is one small Markdown file describing a single user-facing change, dropped in this directory. x release consumes every changeset here into a new CHANGELOG.md section, bumps VERSION, and deletes the consumed files.

Format

bump: minor
type: feat
One or more lines describing the change, in the past-agnostic imperative used in
the changelog. Markdown is fine.
  • bump: — major, minor, or patch (SemVer). The release version is bumped by the highest level among the pending changesets (unless x release <level> overrides it).
  • type: — the Conventional Commit type (feat, fix, perf, docs, …); it becomes the bold prefix of the changelog bullet.

Adding one

Create a file with a short, unique name, e.g. changes/regex-namespace.md. Any filename works except this README.md, which the release step always skips.
