chore(linguist): exclude ReScript from language detection

[hyperpolymath]

Summary

Adds **/*.res linguist-detectable=false to .gitattributes so ReScript files do not dominate GitHub's primary-language detection.

Rationale: Estate-wide policy: ReScript is being migrated to AffineScript. Pending mechanical migration; this PR is the immediate cosmetic fix to stop ReScript dominating GitHub's primary-language detection until the source files are ported.

Changes

• .gitattributes: **/*.res linguist-detectable=false

Part of estate-wide metadata cleanup 2026-05-26.
