Walkthrough

This pull request introduces pikachat Rust package support and OpenClaw extension integration into a Nix flake. Changes include new package builder functions, a Home Manager module for extension installation, documentation describing the deployment surface, and plugin configuration schema extensions for daemon and sidecar versioning.

Changes

Cohort / File(s)	Summary
Nix Flake Packaging flake.nix	Adds three new functions (mkPikachatPkg, mkPikachatOpenclawExtensionSrc, mkPikachatOpenclawExtensionPkg) to build pikachat Rust packages and OpenClaw extension artifacts. Wires pikachat and pikachat-openclaw-extension packages into package set, adds openclawPlugin system-level plugin declaration, and integrates Home Manager module hookup for the extension.
Home Manager Integration nix/openclaw/home-manager.nix	Introduces new Home Manager module with configuration options for programs.openclaw.pikachatOpenclaw, including toggles for daemon/extension packages and installation preferences. Applies home-manager config to install packages and deploy extension tree to ~/.openclaw/extensions/pikachat-openclaw when enabled.
Documentation pikachat-openclaw/docs/nix-openclaw.md	New file documenting the nix-openclaw deployment surface, including available packages, plugin contract, Home Manager module integration, example configuration snippets, and ACP-backed daemon mode guidance.
Plugin Configuration Schema pikachat-openclaw/openclaw/extensions/pikachat-openclaw/openclaw.plugin.json	Adds seven new schema properties: daemonCmd, daemonArgs, daemonVersion, daemonBackend (enum with native/acp options), daemonAcpExec, daemonAcpCwd, and sidecarVersion to support extended daemon and sidecar runtime configuration.

Poem

🐰 A pikachat sprouts in the nix garden bright,
With openclaw wings and extensions in sight,
Home Manager tends with such graceful care,
Daemon configs dance through the air!
