Migrate reposystem ReScript → AffineScript (213 .res files)

[hyperpolymath]

Tracking issue for porting reposystem's ReScript to AffineScript (ReScript is banned-in-new-code per CLAUDE.md, 2026-04-30).

Current state

• 213 .res files: 75 first-party (gui/src, recon-silly-ation, forge-ops/src, tools/dispatcher, tools/hud) + 138 vendored (gui/lib/rescript-webapi/).
• The governance cicd_rules/banned_language_file gate flags all of them. They are baselined in .hypatia-ignore (PR docs: Phase-2 standalone-vs-local verification + ReScript governance baseline #91) so CI is green while this migration proceeds. New .res files are not baselined and remain blocked.

Evidence this is a human effort (not a mechanical transpile)

Ran AffineScript's own res-to-affine --partial over the 75 first-party files with a locally-built toolchain:

• 0 / 75 compile; 0 declarations auto-translated; 397 TODO holes; 151 markers (144 untyped-exception, 7 raw-js).
• WIP skeletons seeded in PR for branch claude/affinescript-migration-wip (migration/affinescript/).

Plan

• Port first-party modules, filling TODO holes (untyped exceptions → Result/Validation; %%raw/@val external → typed extern/effects; module-load side effects → explicit registration), type-checking each with affinescript check.
• Replace vendored gui/lib/rescript-webapi/ with AffineScript's native affinescript-dom (do not hand-port the binding library).
• As each module lands and type-checks, delete its .res and remove its .hypatia-ignore line.
• When the last .res is gone, delete .hypatia-ignore's ReScript section.
