Summary by cubic

Add native Waybar support on Linux/Wayland via a new CLI, extract the plugin engine into its own crate, and add Linux keychain support so plugins can store and read secrets.

• New Features

  • New openusage-waybar binary that outputs Waybar JSON; module text shows remaining %, and percentage reports remaining.
  • Tooltip with colored bars, remaining amounts, reset times, and Pango‑escaped strings.
  • Primary progress respects the plugin manifest’s primaryOrder; falls back to the first progress line.
  • Plugin discovery from standard dirs and OPENUSAGE_PLUGINS_DIR; supports --list, --json, and selecting plugins by ID.
  • README adds Linux/Waybar install guide with config example, env vars table, and a screenshot.

• Refactors

  • Plugin engine moved to openusage-plugin-engine crate and reused by the Tauri app.
  • Keychain host API is cross‑platform; adds Linux read/write using secret-tool (libsecret).
  • Cargo workspace introduced; Cargo.lock added and .gitignore updated for /target.
  • Progress bar builder now takes an explicit remaining percentage for clearer rendering.

Pull request overview

Adds Linux/Wayland (Waybar) support by introducing a standalone Waybar CLI that runs the existing plugin system, and by extracting the plugin engine into a reusable Rust crate that both the Tauri app and CLI can consume.

Changes:

• Extract plugin engine into crates/openusage-plugin-engine and wire src-tauri to use it as a dependency.
• Add openusage-waybar binary crate that runs plugins and outputs Waybar-compatible JSON (with Pango tooltips).
• Add a root Cargo workspace and document Waybar installation/configuration in the README.

Re: markup escaping feedback — fixed in 7412aa1. Added pango_escape() for all plugin-controlled strings before markup interpolation.

Love it but without looking into this or major support, a 7.7k diff PR is incredibly hard to review and keep updated.

I think we'll make the decision to only support macOS to keep things simple, and hope that people will maintain a Linux/Windows port on their own.

Thanks though!
