Block 4-ish for adapters: promote Unreleased → [1.1.0] - 2026-05-26
+ refresh the README catalogue with v1.0 / v1.1 / planned labels.

CHANGELOG.md
  - New [1.1.0] section spans all three themes that landed in this
    release (Themes A, B, D from labdev's v1.x backlog).
  - Theme A entries added (postgres-compose + redis-compose
    env-contribution, docs/protocol.md additions).
  - Theme D entry added (gates/smoke-boot).
  - Existing Theme B entries kept verbatim, now annotated "Theme B"
    in their section headers.
  - Compare link v1.0.0...v1.1.0 appended.

README.md
  - "Available adapters" intro switches from "Bootstrapping phase — actual
    adapters land in labdev's M6" to a real status legend (v1.0 / v1.1 /
    planned).
  - Stacks + addons + gates tables updated with current status + a
    one-line capability summary per adapter.
