Polish for shipping: robust auto-detect, empty state, real icons, end-user README

- cli_usage::default_command now enumerates WSL distros and probes each for
  claude before falling back; no more hardcoded -d Ubuntu.
- New autodetect_claude_command Tauri command + IPC binding so the UI knows
  whether claude is reachable.
- App.svelte: clear 'Claude Code not found' empty state with install link.
- Real icons: scripts/make-icon.py generates a 1024x1024 source.png; runtime
  produces 32/128/256 PNGs and a multi-resolution .ico. README in icons/
  explains how to regen.
- README rewritten for friends: install / requirements / troubleshooting on
  top; build-from-source moved to bottom.

-## What this is *not*
+## Install
 
-It does not call the Anthropic API and cannot show server-side ground-truth caps. The "5-hour" and "weekly" numbers are derived from your local JSONL transcripts — the same data `ccusage` operates on. The cap values shown in the percentage and the warning thresholds are user-configurable in Settings.
+1. **Download** the latest `Claude.Usage.Widget_<version>_x64-setup.exe`
+   from the Forgejo releases page.
+2. **Run the installer.** Windows SmartScreen will warn "unrecognized publisher"
+   (it's not code-signed). Click **More info → Run anyway**.
+3. The widget pops up in the upper-left corner. Drag it where you want.
 
-## Architecture (one paragraph)
+## Requirements
 
-A Tauri 2 app with a Rust backend and a Svelte 5 + Vite + TS frontend. The Rust side enumerates `~/.claude/projects/**/*.jsonl`, tail-parses each file (resuming from a cached byte offset so we never re-parse already-seen lines), dedupes events by `requestId || uuid` (subagent transcripts overlap parents), aggregates into 5-hour blocks (ccusage-equivalent algorithm: `block_start = floor_to_hour(first_ts)`, `block_end = block_start + 5h`, new block on ≥5h gap or end-of-block), computes a rolling 7-day window in the user's local timezone, and emits a `usage-updated` event whenever anything changes. A `notify-debouncer-full` watcher fires on file changes; a 60s `tokio::time::interval` poll backstops it because `ReadDirectoryChangesW` on the WSL `\\wsl$\` 9P mount can miss events. The widget window is frameless, transparent, `alwaysOnTop`, `skipTaskbar`, and 280×360 px; drag via the custom title bar.
+- **Windows 10/11** with [WebView2 Runtime](https://developer.microsoft.com/en-us/microsoft-edge/webview2/)
+  (preinstalled on Windows 11; downloadable on Windows 10).
+- **[Claude Code](https://docs.claude.com/en/docs/claude-code)** installed and signed in.
+  - Native Windows install (`claude.exe` on PATH) → works automatically.
+  - Or installed inside WSL → also works automatically; the widget probes each
+    distro to find one with `claude`.
 
-## Build & run
+## Using it
 
-You need a **Windows** host with the Tauri 2 toolchain — see [Tauri prerequisites](https://v2.tauri.app/start/prerequisites/). Quick version:
+- The big ring shows your **current 5-hour session** percentage with a reset countdown.
+- The bars below show the **rolling weekly** limits (all models + Sonnet only).
+- Per-model breakdown (Opus / Sonnet / Haiku) shows how much of *your local
+  current 5-hour block* came from each — derived from your local Claude Code
+  transcripts. (Anthropic's `/usage` doesn't break this out, so we compute it
+  ourselves.)
+- **↻** button (title bar) — force-refresh `/usage` right now.
+- **⚙** — Settings (custom claude command, refresh interval, autostart, distro override).
+- **×** — quit.
+- The window is **resizable** — drag any edge.
+
+## Troubleshooting
+
+**"Claude Code not found"** — the widget couldn't find a `claude` to run. Make sure
+`claude --version` works in either PowerShell or a WSL shell. If it works in
+a non-default WSL distro, open Settings and set **claude command** to e.g.
+`wsl.exe -d Debian bash -lc claude`.
+
+**Ring shows "no /usage data"** — the spawn worked but Anthropic's output didn't
+match the parser. Open Settings → Test /usage now → expand the *raw output*
+disclosure and file an issue with what's there.
+
+**SmartScreen blocks the installer** — expected; the binary isn't code-signed.
+"More info → Run anyway".
+
+**Autostart toggle doesn't survive reboot** — that's the dev build limitation.
+The released installer registers a stable path so autostart works correctly there.
+
+## Privacy
+
+Everything stays on your machine. The widget:
+
+- Reads your local Claude Code config (`~/.claude/projects/`) for the per-model breakdown.
+- Spawns `claude /usage` to read live percentages — that command Anthropic
+  serves from their backend over your existing Claude Code session, exactly
+  the same as when you type `/usage` interactively. The widget never sees
+  your OAuth token.
+- Stores its own settings at `%APPDATA%\claude-widget\config.json`.
+- Makes no other network calls.
+
+## Building from source
+
+You need a **Windows host** with:
 
 ```powershell
-winget install Rustlang.Rustup OpenJS.NodeJS.LTS
+winget install Rustlang.Rustup OpenJS.NodeJS.LTS Microsoft.VisualStudio.2022.BuildTools
 rustup default stable-x86_64-pc-windows-msvc
-npm i -g pnpm
+corepack enable
-# Also: MSVC C++ Build Tools + Windows SDK (Visual Studio Installer),
+corepack prepare pnpm@latest --activate
-#       and Microsoft Edge WebView2 Runtime (preinstalled on Windows 11).
 ```
 
-Then, from this directory:
+Then in this repo:
 
 ```powershell
 pnpm install
-pnpm tauri dev          # iterate
+pnpm tauri dev    # iterate
-pnpm tauri build        # NSIS installer in src-tauri\target\release\bundle\nsis\
+pnpm tauri build  # produces NSIS installer in src-tauri\target\release\bundle\nsis\
 ```
 
-If you're developing in WSL but building on Windows, the WSL filesystem is mounted at `\\wsl$\<distro>\` from Windows; clone or copy this folder onto the Windows side (or work directly via the UNC path) before running `pnpm tauri build` — Tauri itself needs the MSVC linker.
+Project layout, architecture decisions, and known follow-ups live in
-
+[`memory.md`](./memory.md).
-> **Icons.** Before `pnpm tauri build` succeeds, drop a 1024×1024 PNG into `src-tauri/icons/source.png` and run `pnpm tauri icon src-tauri/icons/source.png` to generate every required size.
-
-## Configuration
-
-`%APPDATA%\claude-widget\config.json` (auto-created on first run):
-
-```jsonc
-{
-  "caps": {
-    "block_tokens": 200000,    // 5h block cap — placeholder default
-    "weekly_tokens": 2000000   // 7d weekly cap — placeholder default
-  },
-  "wsl_distro_override": null, // null = autodetect via `wsl.exe -l -q`
-  "include_native": true,      // also scan %USERPROFILE%\.claude\projects
-  "window_pos": null,
-  "autostart": false
-}
-```
-
-Everything except `window_pos` is editable in the in-app Settings panel (gear icon).
-
-## Verification checklist
-
-1. **Cold parse correctness** — compare `BlockRing` total to:
-   ```bash
-   jq -s '[.[]|select(.type=="assistant")|.message.usage|(.input_tokens+.output_tokens+.cache_creation_input_tokens+.cache_read_input_tokens)]|add' \
-     ~/.claude/projects/<path>/<sessionId>.jsonl
-   ```
-2. **Block boundary** — `scripts\seed-fake-jsonl.ps1 -OffsetHours -6` appends a back-dated synthetic line; confirm it produces a *new* prior block instead of folding into the active one.
-3. **Dedupe** — duplicate one assistant line into the matching `subagents/<id>.jsonl`; total must not double.
-4. **Live tail** — start a real `claude` session in WSL; the ring should tick up within a couple of seconds (debouncer ~250 ms).
-5. **Watcher fallback** — set `WIDGET_NO_WATCH=1` in the env (TODO: wire this up if needed) and append a line; the next 60s poll picks it up.
-6. **Fake feed** — `scripts\seed-fake-jsonl.ps1` writes a synthetic assistant line; UI updates without restart.
-7. **WSL detection** — switch `wsl_distro_override` in Settings to a distro with no `.claude/`; snapshot goes empty.
-8. **Autostart** — toggle on, reboot, confirm widget appears (Task Manager → Startup tab); toggle off, reboot, confirm it doesn't.
-9. **Transparency / drag** — no chrome; title-bar drag moves the window; position survives restart.
-10. **Memory ceiling** — 24h soak, expect 40–80 MB RSS.

+`icon.ico`, plus Android/iOS sizes (we ignore those — desktop only).
