v0.1.0

• Establish 0.1.0 as the SIP Step-2 software baseline for the reusable framework and minimal runnable application.
• Consume the released tool.java-project v0.1.0 toolchain baseline through project.yml, while keeping the committed gitlink and reusable workflow callers pinned to the exact immutable release commit.
• Record the released Java-tooling baseline and its external template.java-project conformance role in the framework documentation.
• Archive failed release candidates as vX.Y.Z-failed, remove the corresponding normal release tag, and never reuse a consumed release version; the next attempt advances the patch version and records the failed attempt in this changelog.
