fix(tasks): send recurrency/reminder as flat top-level params (v1.1.1)

FiZ Ai() encoder does not support nested objects — recurrencyDescriptor
and reminder fields must be top-level params (recurrency=WEEKLY, not
recurrencyDescriptor={recurrency:WEEKLY}). Same fix for reminder fields.
SPEC.md and CLAUDE.md updated to document the flat encoding.
