v0.6.0

Changed

• Relicensed from GPL-3.0 to MIT.
• Supported Minecraft versions consolidated to 1.21.9, 1.21.10, and 1.21.11 from
  a single source tree. Support for 1.21.8 and older is dropped.
• Versioning is now static semantic versioning read from gradle.properties; the
  build no longer derives the version from git tags.
• Auto-swap diagnostics now log at debug level through the mod logger instead of
  printing to the console, so the game log stays clean.

Added

• A documented release pipeline that builds the Fabric and NeoForge jars and
  publishes them to GitHub Releases, Modrinth, and CurseForge from a single
  vX.Y.Z tag, with release notes taken from this changelog.
• A CI workflow that builds, tests, and uploads a snapshot jar on every push and
  pull request to main.

Fixed

• Auto-swap now moves items through server-synced inventory actions instead of
  editing the client inventory directly, so swaps (tools and armor) hold on real
  servers instead of reverting. It also no longer acts while another container,
  such as a chest, is open.
• Activity-aware mode no longer silences danger and critical alerts during
  continuous mining; it quiets only the warn tier, and the danger tier now repeats
  while mining so a tool cannot wear down to breaking unannounced.

Removed

• Per-version release branches and the v...-stable-1.21.x tag scheme, replaced
  by plain vX.Y.Z tags on a single branch.
