v1.25.0

### Changes

- A save in progress can be cancelled, from a Cancel button in the saving mask or with the Escape key, registered at `document_start` so it precedes any page listener (#1994)
- New option bounding the zoom out applied to the page while deferred content is loaded
- The deferred images options are renamed to deferred content, and the section now comes before the network section in the options page
- New option to save the canonical link of the page, which can be turned off
- The MAFF metadata option is renamed and its two defects are fixed: it recovers the original URL and date of the archived page
- The interface shown while saving follows `prefers-color-scheme: dark`
- The icon of the infobar added to saved pages shows a ripple animation (#1504)
- Multi-page archives open on their table of contents and honor the root directory option, and one re-saved from the editor keeps its pages under the same root
- `single-file-core` updated to 1.6.1, which brings zip.js 2.15.0

### Fixes

- Saved pages can no longer submit forms or set a base URI, and `javascript:` URIs are sanitized in every attribute and namespace
- The saving mask is removed when a capture fails, instead of staying on screen with the Escape shortcut still armed
- The Escape key that cancels an area selection is swallowed on the window in the capture phase and no longer reaches the page
- The content script UI is isolated from the page
- The page document is exempt from the resource size cap
- The bytes of a resource are trusted over its declared content type
- Response headers are relayed in full and looked up case-insensitively
- Page content is sent as a Blob rather than an array where the messaging preserves it
- `FileReader` is feature-detected in the extension UI, so importing settings, choosing a custom archive image and saving to GitHub work in Safari with Lockdown Mode enabled
- `build-extension.sh` requires `zip`, and `jq` on MV3, up front instead of attempting `sudo apt install`
