Text rules: auto-capitalization, double-space period, backspace repeat

- TextContext: field purpose/hints and text before the cursor, reported by the backend (KWin content_type + surrounding_text) - TextRules: sentence-start and double-space heuristics, deletion helpers - KeyRepeater: held backspace repeats, then deletes whole words (Ctrl+BS) - Controller keeps a best-guess of the text before the cursor so rules work instantly and in fields that don't report surrounding text - No auto-capitalization or smart punctuation in password/URL/email fields Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
