chore(policy): add the ReScript BANNED row (post-retirement sync) (#63)

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).
