release: publish base-bash-libs v2.2.0 #564

Goal

Publish base-bash-libs v2.2.0 from the reviewed origin/main commit with verified immutable release assets.

Scope

• Move the reviewed Unreleased changelog entries into the dated v2.2.0 section.
• Align VERSION, README release metadata, and lib/bash/base-bash-libs.release.
• Run candidate validation and release-artifact rehearsal.
• Merge the preparation PR, build the final artifact from the merged commit, publish the annotated tag and GitHub Release, and run verify-remote.
• Record checksums, provenance, and handoff evidence here.

Acceptance criteria

• Release-preparation PR passes the complete hosted quality and validation gates.
• Final artifact verification passes against the merged release commit.
• v2.2.0 tag and GitHub Release contain exactly the canonical archive, checksum manifest, SPDX SBOM, and provenance assets.
• Remote verification passes from a clean checkout.

Explicit follow-ups

• The base-bash-libs-demo v0.1.0 update is intentionally deferred to demo Update base-bash-libs references for Base Foundry #38 until this release is immutable.
• Homebrew and Base pin handoffs are recorded here after publication or explicitly tracked as follow-ups.
