Decide the effective generateKey params once via .let when the caller lacks gen_unique_id / REQUEST_UNIQUE_ID_ATTESTATION, instead of mutating var params/parsedParams deep in handleGenerateKey and re-parsing KeyMintAttestation a second time. isAttestKeyRequest now derives from the final parsedParams, closing the staleness flagged in PR #27 review r3308356496.
Behavior is unchanged: no gate between the parse and the old strip site reads INCLUDE_UNIQUE_ID, and the && short-circuits so the permission lookups still run only when the tag is present.
