Hotfix over v1.2.3 for firefox corruption issue

New
* More filter keywords: vg, magic, lorcana, onepiece, figures, aus, uk, american, japanese, az, pricey, budget, trending, recent, latest
* Console hardware aliases: PS2 Slim, PS4 Pro, PS5 Digital, Switch Lite, Switch OLED, Xbox One X, 360 Slim, and more
* Short console nicknames: dc (Dreamcast), sms (Master System), gg (Game Gear), fc (Famicom), xss/series s/series x, 2600, 7800 (Atari)
* Options page warns when a custom URL template is missing the {q} placeholder

Fixed
* Filter syntax (e.g. pal,ps2:zelda) now works from the context menu and keyboard shortcut, not just the omnibox and popup
* Console filters no longer inherit an unrelated saved category -- picking a console now correctly implies video games
* Spaceless aliases like mastersystem and gamegear now resolve correctly
* Firefox theme detection uses runtime check instead of user-agent sniffing
* Options page animations no longer get stuck mid-transition
* Settings writes filter out unknown keys

Internal
* 705 automated tests, ESLint config, i18n message references for extension name and description

v1.2.1 — 2026-05-20

• Selection length cap now defaults correctly when set to zero.
• Minor accessibility and input-handling improvements.

* Magazine / publication filter

Improved

* Popup and setup pages properly await navigation before closing
