docs: catch up CHANGELOG and AGENTS.md with v1.14.41b reality

CHANGELOG drift:
- 'Unreleased' still claimed 'Will become v1.14.41b on release' even
  though the tag was cut and shipped today. Promoted to a proper
  '## v1.14.41b — 2026-05-08' release header (re-ordered above v1.14.41
  to keep reverse-chronological invariant).
- New 'Unreleased' entry records today's docs-only updates (commits
  8083cd1, d01cff3, this commit) which were patched to Docker Hub via
  the API rather than re-tagging.

AGENTS.md drift introduced by the v1.14.41b CI matrix expansion:
- 'CI produces four Docker Hub tags per release' → eight (one tag pair
  per build variant: base, omos, with-pi, omos-with-pi).
- 'all four `load: true` jobs (validate-base, validate-omos, smoke-base,
  smoke-omos)' → all eight (added validate-with-pi, validate-omos-with-pi,
  smoke-with-pi, smoke-omos-with-pi).

DOCKER_HUB.md unchanged (already in sync, regenerator confirms).

 ## Unreleased
 
-**Optional pi as second harness.** Will become `v1.14.41b` on release.
+Docs-only updates that don't trigger a new image build (Docker Hub description was patched live via the API without re-tagging):
+
+- **Docs:** DOCKER_HUB.md `Image Variants` table now lists all four published variants (`latest`, `latest-omos`, `latest-with-pi`, `latest-omos-with-pi`) instead of only the first two. Generator (`scripts/generate-dockerhub-md.py`) HEADER updated to match.
+- **Docs:** DOCKER_HUB.md gains a tailored `pi (alternative/complementary harness)` section covering run, mempalace integration, and persistence — the full README pi section is too large to include verbatim under the 25 kB Hub limit, so a `replace` rule in the generator emits a Hub-tailored excerpt that links out to the gitea README anchor for full build args / extension list / toolkit detail. DOCKER_HUB.md size 24 862 bytes (138 byte headroom).
+- **Docs:** README pi section gains a `### Setup` paragraph mentioning the prebuilt `latest-with-pi` and `latest-omos-with-pi` Docker Hub tags, mirroring the OMOS section's `latest-omos` mention.
+- **Docs:** AGENTS.md tag-scheme paragraph corrected from "four Docker Hub tags per release" to eight (the v1.14.41b CI matrix expansion). Reclaim-disk job list updated from the four pre-pi jobs to all eight current `load: true` jobs.

+**Optional pi as second harness.**
 
 - **Feature:** New `INSTALL_PI=true` build arg installs [pi](https://github.com/mariozechner/pi-coding-agent) as an alternative or complementary harness alongside opencode. Both harnesses share the same mempalace install and palace path — wing/diary entries are mutually visible. Adds ~150 MB to the image. Pi version pinned by `PI_VERSION` (default: latest at build time); `pi update` inside the container does not persist across `--rm` containers — image rebuild is the upgrade path, same contract as `OPENCODE_VERSION`.
 - **Feature:** New `INSTALL_OPENCODE=false` build arg builds an image without opencode (e.g. for pi-only use). Default remains `true`. Existing builds and tags are unaffected.

 - **CI:** `.gitea/workflows/{validate,docker-publish}.yml` extended with `with-pi` and `omos-with-pi` matrix entries. Each release now produces eight Docker Hub tags: `vX.Y.Z[n]`, `latest`, `vX.Y.Z[n]-omos`, `latest-omos`, `vX.Y.Z[n]-with-pi`, `latest-with-pi`, `vX.Y.Z[n]-omos-with-pi`, `latest-omos-with-pi`.
 - **Docs:** README adds a "pi (alternative/complementary harness)" section. AGENTS.md codifies pi install contract, deploy ordering in entrypoint-user.sh, and rationale for not calling mempalace-toolkit's full `install.sh` from container.
