What's New

Codex install target (#9)

• megamemory install --target codex now configures megamemory for OpenAI's Codex CLI/IDE/App
• Primary path uses codex mcp add CLI; falls back to writing TOML directly to ~/.codex/config.toml
• Writes ~/.codex/AGENTS.md with knowledge graph workflow instructions

SQLite concurrency fix (#8)

• softDeleteNode(), hardDeleteNode(), and resolveConflict() now wrapped in transactions to prevent orphaned edges under concurrent multi-process access
• Reentrant transaction support via _txDepth counter
• runWithRetry() with exponential backoff for SQLITE_BUSY errors
• busy_timeout increased from 1000ms to 5000ms
• Graceful SIGINT/SIGTERM shutdown in MCP server
