v0.1.0 - Initial Release

Added

• Initial release of the agent-journal MCP server: a local, project-scoped
  knowledge base and journal for coding agents.
• Knowledge base of immutable, confidence-tracked statements attached to
  entities, with immutable edits and invalidation instead of in-place updates.
• Append-only journal recording what was done and what was proven, with links
  to knowledge-base records.
• Search over both stores via SQLite FTS5 and sqlite-vec, backed by local
  embeddings, with humanized relative timestamps on results.
• MCP tools: memory.search, memory.get, memory.recent, memory.stats,
  memory.guide, memory.agents_md_snippet, kb.upsert_entity,
  kb.add_statement, kb.edit_statement, kb.invalidate, kb.delete, and
  journal.append.
• Automatic project resolution from git remote, worktree, or working directory,
  with per-repo config files under the XDG app config directory.
• --mcp flag to run as a server; bare invocation prints help and --version
  reports the version.
