feat: add Codex CLI, OpenClaw, and MCP-based IDE integrations

Codex CLI: transcript-based integration watching ~/.codex/sessions/,
schema bumped to v0.3 with exec_command support, AGENTS.md context.

OpenClaw: installer wires pre-built plugin to ~/.openclaw/extensions/,
registers in openclaw.json with memory slot and sync config.

MCP integrations (6 IDEs): Copilot CLI, Antigravity, Goose, Crush,
Roo Code, and Warp — config writing + context injection. Goose uses
string-based YAML manipulation (no parser dependency).

All 13 IDE targets now supported in npx claude-mem install.
