Text selection now offers actions beside the selected passage and saved highlights can be edited or removed. Mouse selection no longer turns pages, both EPUB columns are selectable, and PDF mouse selection opens an Annotate/Copy toolbar.

The reader exposes serializable EPUB text ranges and PDF page rectangles for host-owned persistence, plus highlight actions and toolbar/panel builders. Books start in one column with controls hidden. Chrome uses the host theme with single header/footer borders.

Validation: 199 reader tests and 2 example tests passed, reader/example analysis and worker consistency checks passed. A real Chrome/PDFium mouse-drag check confirmed the PDF toolbar and annotation callback. Mobile device acceptance remains unrun.

Closes #7. Supports FR-3_4 and FR-4_1.

Fixed the Linux PDF test timeout in a6db5a8. The failed job logs show that PDFium could not find its shared library or .dart_tool/native_assets.yaml, and its worker left initialization waiting until the test timeout. The test now loads the explicit library path from Flutter's generated build/native_assets/<os>/native_assets.json, validates that the file exists, and bounds initialization/document operations to 15 seconds. The test itself has a one-minute timeout.

Both selection layouts pass in an isolated checkout without the Dart native-assets map, and analysis/formatting pass. The Linux CI rerun is pending. This commit changes test setup only.

Fixed the browser smoke timeout in ecc55c4. The script still expected controls to be visible immediately after opening each book, and expected Automatic rather than Single columns. It now waits for book content, verifies the controls start hidden, taps to reveal them, and checks the new single-column default. The keyboard-only chapter navigation scenario starts in the default focus mode.

Validated the complete npm test browser smoke suite against a fresh flutter build web, using the installed Playwright Chromium. All worker, EPUB, file import/error, focus/keyboard, responsive settings, PDF navigation/scroll/refit and theme-menu checks passed. Node syntax and diff checks passed. CI run 45 also confirms the preceding PDFium fix passed both Flutter test steps on Linux. The new CI run is pending.
