Implement the Vec.* half of #25 under the proper (de-abbreviated) name Vector, unblocking it with a self-contained value type instead of waiting on the full #1 type system. A Vector is two Q16.16 fixed components (x, y) packed into one i64 — a true by-value type that lives in a register and never allocates (reuses the new `long`/i64 support; llty maps `Vector` to i64). Fifteen operations, all deterministic fixed-point reusing fx_mul/fx_div/fx_lerp and the @fn_fx_* prelude: make/zero/x/y, add/sub/scale/dot, length/distance/normalize/lerp, rotate/angle/from_angle. New selfhost/emit_vector.ludic (wired into emit_ns_call + the frag list), the `Vector` primitive type in llty and the grammars/LSP/JetBrains tokens, docs (type-vector + 15 Vector.* pages + section), and a registered test. Reseeded; C-free fixpoint holds; all suites green (45/25/29); site + check.py OK. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

| vector-dot | Vector.dot | vector | namespace-method | Vector.dot | Vector.dot(a, b) -> fixed | The dot product of two vectors. | 7 | Vector | dot |
Returns the dot product axbx + ayby as a fixed. Zero when the vectors are perpendicular; use it to project one vector onto another or to test facing.
