v0.99.54

Refine the channel header and message input, and add independent text sizing for the buffer area.

• Desktop channel headers show More actions, nick list, Leave, and Settings in that order. Pin, Mute, Search, and Detach are available from the three-dot menu when supported by the server.
• Remove the close buttons from mobile sidebar headers and the connection-status dot from network rows.
• Add Appearance → Message input → Touch the edges, enabled by default. The input spans the chat pane with square corners; turn the option off to restore the rounded, inset input.
• Replace interface-wide text scaling with Messages → Text size. Choose any whole-pixel size from 10 to 20 px, with 15 px as the default. Headers, sidebars, dialogs, and the composer keep their usual sizes.

Validation: TypeScript, ESLint, Prettier, 612 unit/component tests, 53 browser tests, and the production build passed. The 10 optional screenshot tests are skipped by default.
