🎨 Added typing ` over selected text to format it as inline code - #32551
Typing a backtick while text is selected in the editor now toggles inline code on the selection, the same as Ctrl/Cmd + Shift + K. It works in every editor where that shortcut does.
Typing a backtick with an eligible text selection now applies inline-code formatting. The handler leaves other keys, collapsed selections, non-range selections, modified keypresses, and active composition to the existing behavior. End-to-end tests cover selection behavior, toggling, undo and redo, literal insertion, and code-card content.

Merge Risk: Low · up to b60a8
The shortcut has two bounded limitations: dead-key backticks do not apply formatting, and holding backtick can toggle formatting repeatedly. Mergeable with owner awareness and follow-up for these input cases.

Explanation
The title says typing a backtick over selected text formats the selection as inline code. The changeset covers this: the KEY_DOWN_COMMAND handler in KoenigBehaviourPlugin.tsx formats non-collapsed range selections as code on a backtick, and the e2e tests check it. The title names the main change. The leading emoji and the unclosed backtick in the title are minor style issues.
Full details: Description check
Explanation
The description says that typing a backtick over selected text now toggles inline code, the same as Ctrl/Cmd + Shift + K. The changeset adds this behaviour in KoenigBehaviourPlugin.tsx and tests it in the e2e suites. The description also links the related Linear issue.

Explanation
PASS. The PR adds a Lexical keyboard-command handler that reads a typed DOM event and dispatches the existing internal FORMAT_TEXT_COMMAND. It adds no HTTP/API, env/config, database/filesystem, queue, webhook, or external event boundary consumption. The changed production lines add no any, unchecked as, @ts-ignore, or @ts-nocheck, and no duplicated Zod-described type.

Dead-key backtick input does not apply code formatting.
The new branch matches only a keydown whose key is a literal backtick. On a dead-key layout, the backtick keydown reports key === 'Dead', so the branch does not run. The completed backtick then arrives as ordinary text input, which this branch does not intercept, and it is not applied as code. The PR description says the behavior works wherever Ctrl/Cmd + Shift + K works, so this gap contradicts that claim.
Either handle the composed backtick in the text-input path, or narrow the PR description so it does not claim parity with Ctrl/Cmd + Shift + K on every layout.

Ignore auto-repeated backtick keydowns in the inline code shortcut.
Holding the backtick key sends repeated keydown events. Each one dispatches FORMAT_TEXT_COMMAND on the still-selected text, so inline code toggles on and off. Dispatch the command only for the first press. For repeats, still call preventDefault() so no backtick is inserted.
