v0.7.0 — Sync, Tri-Modal Query, OPFS, Integrations

AgentDB v0.7.0

Major New Features

• CRDT-Based Sync Engine — Replicate AgentDB instances with Hybrid Logical Clocks, operation logs, and configurable conflict resolution (Last-Writer-Wins / First-Writer-Wins)
• Tri-Modal Hybrid Query — Blend vector ANN + graph traversal + FTS BM25 in a single query with tunable alpha/beta/gamma weights
• WASM OPFS Persistence — Browser databases now survive page reloads via the Origin Private File System API (load-save pattern with SQLite serialize/deserialize)
• LangChain Integration — langchain-agentdb package implementing VectorStore + BaseChatMessageHistory
• LlamaIndex Integration — llamaindex-agentdb package implementing BasePydanticVectorStore + BaseChatStore
• Ruby SDK — Full FFI bindings (40+ functions) with idiomatic Ruby API, RSpec test suite

CLI Improvements

• agentdb version — print version + target triple
• agentdb export <path> [--table <name>] — dump database as SQL statements
• agentdb completions --shell <bash|zsh|fish|powershell> — generate shell completions

Test Coverage

• 73 new async API tests (Rust)
• 91 new Node.js tests covering full API surface
• Python test suite (10 test classes)
• 16 sync module tests
• 8 tri-modal query tests

Dependency Migrations

• rand 0.8 → 0.10 (thread_rng → rng, gen → random)
• criterion 0.5 → 0.8 (removed deleted html_reports feature)

CI/CD Fixes

• Fixed Snap/WinGet/Chocolatey publish workflows (root cause: actions/checkout@v7 doesn't exist)
• crates.io publish: pinned MSRV 1.95.0, added --locked
• Coverage threshold raised to 80%, now includes async+ffi code paths
• Node.js smoke test class name bug fixed

Documentation

• ROADMAP.md aligned with actual v0.6.0 release content
• README roadmap table corrected
• Manual publish steps documented for Snap/WinGet/Chocolatey/crates.io
