ci: comprehensive build + test + push workflow for all packages

## Problems fixed:
- Workflow only tested mem-ingest, missing mem-cli + mem-llm + mem-store errors
- No early error detection (build step missing)
- No linting/code quality checks
- Docker operations ran on all events (should be push/dispatch only)

## Changes:
- ✅ Build all packages (cargo build --all)
- ✅ Test all packages (cargo test --all --lib)
- ✅ Clippy linting (catches E0106, E0425, E0432, E0433 at compile time)
- ✅ Docker build/push only on main/dispatch (not on PRs)
- ✅ Full output (150 lines) for debugging
- ✅ Conditional gates for push-only operations
