Add --no-db mode: JSONL-only operation without SQLite

Implement --no-db mode to avoid SQLite database corruption in scenarios where the same .beads directory is accessed from multiple processes (e.g., host + container, multiple containers). Changes: - Add in-memory storage backend (internal/storage/memory/memory.go) - Implements full Storage interface using in-memory data structures - Thread-safe with mutex protection for concurrent access - Supports all core operations: issues, dependencies, labels, comments - Add JSONL persistence layer (cmd/bd/nodb.go) - initializeNoDbMode(): Load .beads/issues.jsonl on startup - writeIssuesToJSONL(): Atomic write-back after each command - detectPrefix(): Smart prefix detection with fallback hierarchy 1. .beads/nodb_prefix.txt (explicit config) 2. Common prefix from existing issues 3. Current directory name (fallback) - Integrate --no-db flag into command flow (cmd/bd/main.go) - Add global --no-db flag to all commands - PersistentPreRun: Initialize memory storage from JSONL - PersistentPostRun: Write memory back to JSONL atomically - Skip daemon and SQLite initialization in --no-db mode - Extract common writeJSONLAtomic() helper to eliminate duplication - Update bd init for --no-db mode (cmd/bd/init.go) - Create .beads/nodb_prefix.txt instead of SQLite database - Create empty issues.jsonl file - Display --no-db specific initialization message Code Quality: - Refactored atomic JSONL writes into shared writeJSONLAtomic() helper - Used by both flushToJSONL (SQLite mode) and writeIssuesToJSONL (--no-db mode) - Eliminates ~90 lines of code duplication - Ensures consistent atomic write behavior across modes Usage: bd --no-db init -p myproject bd --no-db create "Fix bug" --priority 1 bd --no-db list bd --no-db update myproject-1 --status in_progress Benefits: - No SQLite corruption from concurrent access - Container-safe: perfect for multi-mount scenarios - Git-friendly: direct JSONL diffs work seamlessly - Simple: no daemon, no WAL files, just JSONL Test Results (go test ./...): - ✓ github.com/steveyegge/beads: PASS - ✗ github.com/steveyegge/beads/cmd/bd: 1 pre-existing failure (TestAutoFlushErrorHandling) - ✓ github.com/steveyegge/beads/internal/compact: PASS - ✗ github.com/steveyegge/beads/internal/rpc: 1 pre-existing failure (TestMemoryPressureDetection) - ✓ github.com/steveyegge/beads/internal/storage/sqlite: PASS - ✓ github.com/steveyegge/beads/internal/types: PASS - ⚠ github.com/steveyegge/beads/internal/storage/memory: no tests yet All test failures are pre-existing and unrelated to --no-db implementation. The new --no-db mode has been manually tested and verified working. 🤖 Generated with [Claude Code](https://claude.com/claude-code) via [Happy](https://happy.engineering) Co-Authored-By: Claude <noreply@anthropic.com> Co-Authored-By: Happy <yesreply@happy.engineering>
