chore(policy): add the ReScript BANNED row (post-retirement sync)

[hyperpolymath]

Estate-wide policy sync (task: BANNED-row campaign, 2026-08-31).

ReScript is retired outside the enclave (owner ruling 2026-08-31: rescript, rescript-ecosystem, and the proven adapters stay ReScript; nothing else). This repo's language-policy table in .claude/CLAUDE.md predated that ruling.

• Adds | ReScript | AffineScript | to the BANNED table (whole-line insert after the TypeScript row, extra columns mirrored).
• Where the Python row still recommended ReScript as a replacement, rewrites it to AffineScript.

Doc-only change; verified estate-wide by an origin-side GraphQL scan of all 428 non-archived repos (52 repos in this sweep).

📝 Walkthrough

Summary by CodeRabbit

• Documentation
  • Updated the language policy to list ReScript as banned.
  • Added AffineScript as the recommended replacement, with the migration path: RS/TS/JS → AffineScript → typed-wasm.

Walkthrough

The language policy documentation adds a BANNED-table row for ReScript. The row lists AffineScript as the replacement and defines the migration path as “RS/TS/JS → AffineScript → typed-wasm”.

Changes

Language policy

Layer / File(s)	Summary
ReScript policy entry .claude/CLAUDE.md	The BANNED languages table adds a ReScript row with its replacement and migration path.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: 🔵 Low · up to bfabc

The policy file now contains two ReScript ban entries, which can split migration guidance and lead to inconsistent repository-policy interpretation. This is a localized documentation issue requiring owner follow-up before or alongside merge.

Poem

A rabbit checks the policy page
One ReScript row joins the stage
AffineScript marks the way
Typed-wasm ends the day
The table grows, neat and clear

Remove the duplicate ReScript policy row.

Line 158 already defines the ReScript ban and migration rule. Keeping both rows splits the policy across duplicate entries and can cause inconsistent interpretation. Update the existing row instead of adding a second ReScript row.
