- Add QmdMemoryBackend class implementing MemoryBackend interface with async agent execution
- Backend executes QMD memory operations via subprocess spawn with configurable command/args
- Graceful fallback to readonly mode on write failures with error logging
- Add readWithoutFetch() and bootstrap() helpers to ProjectMemory for backend-aware read/bootstrap semantics
- Wire QMD backend into TaskStore.create() and memory initialization
- Export QmdMemoryBackend and BackendCapabilities from @fusion/core
- Add comprehensive tests for QMD backend and project memory helpers
- Update project memory instructions to encourage selective writes instead of unconditional appends
- Instruct agents to consolidate existing entries rather than add duplicates
- Add guidance to skip memory updates when no durable learnings were discovered
- Clarify what qualifies as durable learnings vs task-specific trivia
- Update user-facing memory documentation to reflect new selective behavior
- Add test coverage for selective memory write instructions
- Add project-memory module in @fusion/core with read/write/resolve helpers and upsert-on-store hook
- Bootstrap project memory during task creation (store) with structured task context
- Inject resolved project memory into executor and triage agent system prompts
- Add comprehensive tests for project-memory module, store integration, and agent prompt changes
- Document project memory architecture and usage in README
