Update version strings in extension manifests to reflect the new release date. chrome/manifest.json and edge/manifest.json: 2026.04.23 -> 2026.04.24; firefox/manifest.json: 2026.4.23 -> 2026.4.24. No other functional changes.
Add a complete Edge extension under edge/ (manifest, popup, CSS, JS, locales, assets, LICENSE) and a change.log. Update README with Edge/mobile notes and simplify content. Update GitHub Actions workflow to read edge/manifest.json version, package Edge builds, and include Edge asset in the release summary (also bump default release_tag). Minor update to firefox/js/oper.js and include .DS_Store change.
Update README.md to replace the previous "等待上架" Firefox status with the actual add-on URL (审核中): https://addons.mozilla.org/zh-CN/firefox/addon/memos-bber/. Add macOS .DS_Store metadata files at repository root and firefox/ (binary files).
Add Firefox icon assets and update manifest to use the new icon files and opt-out data_collection_permissions. Replace minified view-image.js with a modern, readable implementation (style injection, accessible controls, keyboard navigation, and better DOM handling). Simplify background popup logic to call chrome.browserAction.openPopup directly. Remove the packaging section from README to clean up docs.
Add a GitHub Actions workflow (package-extensions.yml) to build and upload Chrome/Firefox packages (store and offline artifacts) on manual trigger or when pushing v* tags. Update README with packaging instructions. Reorganize extension sources into chrome/ and firefox/ directories, add Firefox-specific files (manifest, locales, assets, CSS, LICENSE), and bump Chrome manifest version to 2026.04.23. Also modify js/oper.js (moved to chrome/js) to improve proportional editor resizing: add drag-to-resize, scale clamping/persistence (localStorage + chrome.storage.sync), pointer event handlers, and max-scale computation.
