Vijay Janapa Reddi b8183404b8 chore(release): shared versioning infrastructure
Lays foundation for unified release versioning across MLSysBook
publishable artifacts. Pure additions — no existing builds, configs,
or sources are touched.

scripts/version/release.py
  Python CLI with helpers:
  - compute-id: semver bump from previous tag (patch/minor/major/none/explicit)
  - compute-hash: deterministic SHA-256 over input directories with per-file index
  - emit-release: writes releases/<project>-<id>/release.json (canonical artifact)
  - emit-manifest: writes the build-time manifest the deployable bundles
  Tier A (citable) emits per-file Merkle index; Tier B (lite) is flat.

scripts/version/schema.json
  JSON Schema for release.json. Validates project/tier/release_id/release_hash
  + Tier A's files[] index. Used by validators in CI.

shared/release/release-pill.html
  Footer snippet — fetches deployable manifest at runtime, renders
  "v0.1.0 · Apr 26, 2026" pill. Configured per-project via
  <meta name="release-manifest"> tag. Silent on any fetch failure.

shared/release/release-card.html
  About-page snippet — fuller release-identity card with
  click-to-copy hash. Same fetch + meta-tag conventions.

shared/release/README.md
  Operator-facing contract documentation.

.github/workflows/_release-prepare.yml
  Reusable workflow_call. Validates confirm == "PUBLISH", computes
  new_release_id from previous tag + bump (delegates to release.py
  for canonical math). Outputs new_release_id/new_tag/previous_*
  for caller's downstream build and finalize steps. Refuses to
  re-tag existing releases (citation integrity).

Caller workflows still own their build commands and tag/release
creation; this only standardizes the input shape and version math.
