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

ReScript is retired estate-wide (enclave ruling 2026-08-31: only the
rescript/rescript-ecosystem/proven-adapter repos remain ReScript). This syncs
the language-policy BANNED table: adds | ReScript | AffineScript | after the
TypeScript row, and where present rewrites the Python replacement row to no
longer recommend ReScript.
