ZenNotes for Android 1.1.17 (versionCode 19): app core 2.46

A pin release, in step with iPhone 1.9.8. The shell is unchanged; the app core moves from 2.45.0 to 2.46.0 (pinned to da59c372, the v2.46.0 tag commit), and five of its ten changes reach the phone.

What ships

• App core 2.46 (0452b63, with the pin): comment threads with names, a reply filed under the comment it answers; Date… in the @ menu opens a calendar; saved Tasks filters as chips under the Tasks header; the Kanban Folder board (one column per note folder, or one folder's children); display math inside callouts and Typst formulas at KaTeX's size. Not on the phone: the desktop-only keymap changes, the CLI fix and the remote-template routes.
• Version bump 1.1.17 / versionCode 19; package.json and the bridge's appVersion follow. Native side unchanged (no new permissions, services, or data collection).
• Release pack docs/releases/v1.1.17/ (8c96c8d).

Verification (2026-09-08)

• npm test 38/38 and npm run typecheck clean on 8c96c8d, source prepared at the pin.
• No release build or Play submission as part of this PR.

Same round ships as ZenNotes for iOS 1.9.8.
