List only after-1.0 work in the README roadmap (closes #208)

The README roadmap and the TODO.md Next Step still described finished
1.0 work as remaining. The roadmap now lists only work planned after
1.0. The security item says the encryption and blob-generation code was
reviewed before 1.0 with every finding fixed, and keeps an outside audit
as after-1.0 work rather than a blocker. The error-condition item is
gone because every failure case it listed now has a fault-injection
test. TODO.md says the 1.0 work is complete on next and that merging to
main and tagging are the owner's; Future Steps points to the roadmap.

Judgement call: dropped the human-readable size flags item; no command
flag takes a raw-integer size.

Model: opus-5-5
