v0.2.7

Changes

• Reuse Codex app-server sessions through the shared CODEX_HOME Unix socket by default.
• Add appServerOptions.mode for auto, attach, launch, and stdio-isolated lifecycle control.
• Allow appServerOptions.codexHome so users can point Diffwarden at a stable alternate Codex home.
• Preserve ephemeral read-only Codex review turns while documenting that shared mode inherits Codex auth, config, plugins, apps, and daemon state.
• Keep the previous temporary CODEX_HOME stdio behavior available as stdio-isolated.
• Add regression coverage for shared socket reuse, bad socket upgrade handling, and isolated auth-source preflight.
