modisa 0.3.0

• The client applies attach's view and the replay's screens in stream order
• Tests: wait for a just-spawned process's command line (Linux sets it up late in exec)
• Linux: a process's children from every thread's list, not only the main thread's
• Views (UI 3) in the client: ratatui's own widgets, and modisa view render
• Views (UI 3): the server checks UI 3's elements, the schema and the client library speak them
• Views (UI 3): the spec, and the reader for its colours, styles, constraints, text and blocks
• modisa in Rust: one native binary replaces the TypeScript/Bun build [minor]
• Plugin views: element trees a plugin shows, drawn by modisa in your theme
