feat(obsidian): register wiki vault with cross-platform path

[shunkakinoki]

Summary

• Generate obsidian.json dynamically via Nix using config.home.homeDirectory so the vault path resolves correctly on both kyber (/home/ubuntu) and galactica (/Users/shunkakinoki)
• Set open = true on the vault so the headless daemon auto-opens it on startup, enabling the Obsidian CLI
• Enable the config on both isKyber and isGalactica (was kyber-only)

Test plan

• Verified obsidian help works on kyber after make switch + service restart
• Verify on galactica after next make switch

Summary by cubic

Registers the Obsidian wiki vault with a cross‑platform path and auto‑opens it on startup to enable the headless obsidian CLI. Fixes “Vault not found” on kyber and galactica.

• New Features
  • Dynamically generates obsidian.json via Nix using config.home.homeDirectory so the vault path resolves on both hosts.
  • Enables the config on kyber and galactica; sets open = true so the daemon opens the vault automatically.

Walkthrough

The Obsidian module configuration is refactored to dynamically generate its JSON configuration file using Nix, expanding host support from Kyber to include Galactica, and defining a wiki vault path. Additionally, the dotagents git submodule reference is updated to a newer commit.

Changes

Cohort / File(s)	Summary
Obsidian Configuration config/obsidian/default.nix	Module updated to accept config and pkgs parameters; obsidian.json now dynamically generated via pkgs.writeText and builtins.toJSON instead of using static file; enablement condition expanded to support both Kyber and Galactica hosts; generated configuration explicitly sets cli = true and defines vaults.wiki with path derived from config.home.homeDirectory.
Submodule Reference dotagents	Git submodule commit reference advanced to a newer version.

🐰 A rabbit hops through configs new,
Obsidian blooms in JSON dew,
Galactica joins the vaulted way,
While agents dance in fresh array. 🌙✨

Mesa Description

TL;DR

Dynamically generate obsidian.json via Nix for cross-platform vault path resolution, enable auto-opening for the Obsidian CLI, and activate the config for both kyber and galactica.

What changed?

• Generated obsidian.json dynamically via Nix using config.home.homeDirectory to correctly resolve the vault path on kyber and galactica.
• Set open = true on the vault to enable the headless daemon to auto-open it on startup, enabling the Obsidian CLI.
• Enabled the configuration on both isKyber and isGalactica (previously kyber-only).

Code Review

This pull request updates the Obsidian configuration to support both isKyber and isGalactica hosts by dynamically generating the obsidian.json file and updating the dotagents subproject. Feedback highlights that the Obsidian package and services may still be restricted to isKyber in other modules, and that the configuration file path needs to be adjusted for macOS (isGalactica) to match its platform-specific location instead of the XDG standard.

[gemini-code-assist]

The enabled flag is used here to deploy the configuration file, but the obsidian package and its associated headless service are still restricted to isKyber in home-manager/modules/obsidian/default.nix and home-manager/services/obsidian/default.nix. If you intend to use the Obsidian CLI on galactica, you will likely need to enable the package there as well, though the current shim's dependency on xvfb-run and the systemd service are Linux-specific.

[gemini-code-assist]

On macOS (isGalactica), Obsidian expects its configuration file at ~/Library/Application Support/obsidian/obsidian.json rather than the XDG standard ~/.config/obsidian/obsidian.json. To ensure the vault is correctly registered on both platforms, you should target the platform-specific path for macOS.

  xdg.configFile."obsidian/obsidian.json" = {
    source = obsidianJson;
    enable = isKyber;
  };
  home.file."Library/Application Support/obsidian/obsidian.json" = {
    source = obsidianJson;
    enable = isGalactica;
  };
