 - CI: bumped `actions/checkout` v4→v5 and `actions/setup-python` v5→v6 onto the Node 24 runtime ahead of GitHub's Node 20 removal, and added a `node --check` syntax gate for the dashboard's `app.js`.
 - CI: added a `Build & release installer` workflow (manual dispatch or `v*` tag) that PyInstaller-freezes the four executables, compiles the Inno Setup installer, and uploads the artifact (attaching it to a GitHub Release on tag). Uses Node-24 actions (`checkout@v5`, `setup-python@v6`, `upload-artifact@v7`).
 - Installer build: `build.ps1 -BundleAhk` now fetches AutoHotkey v2 from its GitHub release (pinned 2.0.26) instead of `autohotkey.com`, which began returning a Cloudflare bot-challenge page to non-browser clients (the download succeeded but `Expand-Archive` failed on the HTML). `autohotkey.com` is kept as a fallback.
+- Installer compile: `installer.iss` now actually compiles end-to-end (the build workflow's first green run). Three latent bugs, each masking the next, are fixed: (1) a trailing `; ...` comment on the `MinVersion` directive was parsed as part of the value (Inno Setup only treats `;` as a comment at the start of a line); (2) no `SourceDir` was set, so Inno resolved every repo-root-relative `Source`/`SetupIconFile`/`OutputDir` against the script's own `installer\` directory — now `SourceDir=..`, which also lands the output at `<root>\out` where the build script and CI look for it; (3) an `{app}` Inno constant inside a Pascal `{ }` doc-comment in `[Code]` closed the comment early (these comments don't nest). Also ships `scripts\assets\*` (the tray `.ico` the AHK loads at runtime), which `[Files]` had omitted.
