port(src/ui/tea/git_scripts_gui.affine): ReScript surface -> AffineScript (Refs #229) (#9)

Oracle-validated Tier-1 port (affinescript main @ #229 canonical map,
docs/RESCRIPT-ELIMINATION.adoc):
- List(T) -> [T]  (1 occurrence)
- expression-position record literals { ... } -> #{ ... } (the record
  sigil, spec.md:414-421). Match record-PATTERNS and struct/enum/type
  decl bodies correctly left as { } (sigil is expression-literal-only,
  oracle-confirmed).

Verified: `affinescript main check src/ui/tea/git_scripts_gui.affine` -> Type checking passed
(was: parse error / DRIFT-SYNTAX pre-port). Self-contained file, no
imports. Refs #229 (estate-wide, sequenced, human-gated — not Closes).
