Introduce first-run setup flow and live chrome theme syncing.
- Add first_run_state.cpp/.h to read/write a first_run_state.json under user data and decide whether to show the setup UI.
- Wire first-run logic into NebulaController: track first_run_setup_active_, create initial setup tab, defer/bring up chrome browser accordingly, and add CompleteFirstRunSetup() to persist state and finish setup.
- Add SendThemeToChromeSurfaces() and handle "theme-update" and "complete-first-run" chrome commands; restrict setup completion to setup frame.
- Expose GetFirstRunStatePath() and GetSetupUrl() in UI path helpers and include the state file in the build list (CMakeLists.txt).
- Update chrome UI: new CSS variables and styles for tabs/url-bar; chrome.js can apply themes (applyTheme), persist/load theme, and listen for storage updates to apply theme changes live.
- Update customization.js, settings.js, and setup.js to normalize/persist themes, send theme updates to the native host (or fallback), and communicate completion via the native bridge when available; include customization.js in setup.html.
These changes allow the app to run an interactive first-run setup and keep the separate chrome UI in sync with user-selected themes.
Track menu popup visibility and propagate zoom level to the popup. Add menu_popup_visible_ flag, SendMenuPopupZoom(), and call it when creating/showing the popup and when adjusting zoom. Make CreateNewTab accept an optional URL and route popup/new-tab flows to it. Prevent per-tab child closes from triggering app shutdown by tracking closing_tab_browsers_ and adding ForgetClosingTabBrowser(). Treat MenuPopup role specially when enabling frame hit-testing.
Platform: remove usage of ApplyRoundedBrowserRegion and switch menu popup sizing to use resized client_size helpers (consolidate calculations across Win/Mac/Linux). UI: update menu-popup CSS/JS (new styling, font, zoom formatting API via NebulaMenuPopup.setZoomLevel), wire settings to use nebulaNative.postMessage for new-tab, and remove the static menu-popup.html. Misc: small chrome CSS/JS tweaks and ensure chrome state includes zoomLevel.
Introduce support for an internal nebula:// URL scheme and internal page routing (ResolveInternalUrl / ToInternalUrl), including dedicated slugs for home, settings, downloads, big-picture, gpu-diagnostics, insecure and a 404 fallback. Wire internal resolution into browser creation and tab navigation so internal pages load from local UI files. Add an insecure-warning interstitial flow with a navigate-insecure command and a one-shot bypass set (ShouldBypassInsecureWarning) so content can request navigating to an HTTP target after user confirmation. Harden BrowserClient handling to resolve Chromium new-tab and nebula internal URLs, redirect HTTP to the insecure warning when appropriate, and handle 404 responses by loading the internal 404 page. Update chrome UI behavior to hide internal home URLs, accept nebula:// in navigation input checks, and add a GPU Diagnostics page (revamped UI + diagnostic scripts) plus menu entry. Misc: improve URL utilities (scheme checks, percent-encoding, decorations), fix 404 display text, adjust menu popup size, tweak window frame styling (DWM attributes) and remove branding block from chrome UI CSS.
Introduce core application structure and browser management: add NebulaController and run entry (src/app/*) to centralize window, tab and CEF lifecycle logic; implement TabManager and NebulaTab (src/browser/*) for tab creation, navigation and state tracking; add URL utilities (NormalizeNavigationInput, JsonEscape) and CEF browser client glue (src/cef/browser_client.cpp/.h) to forward chrome commands and content events. Update app/main.cpp to delegate startup to nebula::app::RunNebula. Add UI assets (chrome.html, chrome.css, chrome.js, lucide, menu-popup updates) and remove obsolete nebot.html. Update CMakeLists to include new sources, add ${CMAKE_SOURCE_DIR}/src to includes and link dwmapi on Windows. Overall this refactors startup and splits responsibilities for cleaner tab and browser lifecycle handling.
