feat: split-base build pipeline (parallel, manual-trigger only)

Two-Dockerfile split-base build alongside the existing single-Dockerfile pipeline. Goal: cut CI wall clock from ~165-180min to ~30-40min on typical version-bump-only releases by reusing a base image across the four variants. Files added: - Dockerfile.base variant-independent layers (apt, locales, AWS CLI, Node.js, mempalace, gitea-mcp, user setup, chromadb prewarm, ENVs, entrypoints). - Dockerfile.variant FROMs ${BASE_IMAGE} and adds opencode / pi / omos / Go installs gated by INSTALL_* args. Each npm install -g uses NPM_CONFIG_PREFIX=/usr per-RUN to keep baked binaries off the volume- shadowed ~/.pi/npm-global path inherited from base. - .gitea/workflows/docker-publish-split.yml workflow_dispatch-only pipeline: base-decide -> build-base (conditional) -> smoke-* (4 parallel) -> build-variant-* (4 parallel) -> promote-base-latest -> update-description. Hash-driven base reuse: if base-<sha> already exists on Docker Hub, the build is skipped entirely. Inputs: release_tag (test tag suffix, default v0.0.0-split-test) and promote_latest (default false; gates latest-* aliases and Hub description update). Files unchanged: - Dockerfile, docker-publish.yml, validate.yml all left in place so the production tag-push pipeline keeps working untouched. Migration plan (in CHANGELOG Unreleased): 1. workflow_dispatch test run with promote_latest=false; verify the four variant images smoke-pass and have plausible sizes. 2. Compare manifest digests against the same-version output from the production pipeline (independent test run on the same commit). 3. Once verified across 1-2 release cycles, swap docker-publish-split.yml to on: push: tags: v* and retire docker-publish.yml. AGENTS.md and CHANGELOG.md updated with file roles and the migration plan. Production pipeline behavior is bit-for-bit unchanged on this branch.

+# opencode-devbox — variant image
+#
+# FROMs a base-<hash> image produced by Dockerfile.base and adds only
+# the variant-specific tools (opencode, pi, oh-my-opencode-slim, Go).
+#
+# The four published variants are produced from THIS Dockerfile by
+# varying build args:
+#
+#   variant            INSTALL_OPENCODE  INSTALL_OMOS  INSTALL_PI
+#   ─────────────────  ────────────────  ────────────  ──────────
+#   base               true              false         false
+#   omos               true              true          false
+#   with-pi            true              false         true
+#   omos-with-pi       true              true          true
+#
+# Pass `--build-arg BASE_IMAGE=<repo>:base-<hash>` to select the base.
+# The CI workflow computes the base hash from Dockerfile.base + rootfs/
+# + entrypoint*.sh and feeds it in.
+#
+# IMPORTANT: the base image sets NPM_CONFIG_PREFIX to
+# /home/developer/.pi/npm-global so runtime `pi install npm:...` and
+# `npm install -g` by the developer user lands on the named volume.
+# At BUILD time we want the baked binaries on /usr so they survive the
+# volume mount. Each `npm install -g` below therefore prefixes the
+# command with `NPM_CONFIG_PREFIX=/usr`.
