feat: complete M0.1-M0.4 phases

M0.1 - Cargo workspace + crate skeletons - 6-crate workspace with correct dependency direction - CI/CD pipeline with GitHub Actions - Integration tests verifying build and dependency structure M0.2 - Domain types and sha256 identity - Level (L0, L1, L2) enum with proper serde formatting - Role enum (User, Assistant, ToolResult, System) - Record, Chunk, and MemoryNode domain types - Content-hash identity system ensuring rebuild idempotence - Newtypes (ProjectId, QueryId, RunId) with validation - Round-trip serde tests for all types M0.3 - RecordSource trait + ChunkPolicy - RecordSource trait for streaming record sources - Chunk policy with token budgets and boundary modes - TokenCounter trait with CharsOverFourCounter stub - Chunking stream that respects budgets without splitting records - VecSource for testing - Integration tests verifying lossless chunking and budget adherence M0.4 - Tokenizer-backed chunk sizing - Vendored Qwen2 tokenizer with hash verification - QwenTokenCounter implementing proper token counting - Hash guard that fails on modified tokenizer - mem tokens CLI subcommand for token counting - Integration tests with known string counts, hash guards, and budget verification Total: 19 integration tests passing, all phases verified to compose correctly Workspace builds cleanly with no clippy warnings
