feat(api): add get_current_window call

Add prof_get_current_window API to retrieve the title of the currently active window, matching the titlebar display.

The feature is especially useful to track currently used plugin window.

+ *
+ * Message buffer implementation for CProof.
+ *
+ * This module provides an in-memory buffer for managing active chat entries in the
+ * console-based XMPP client. Separate from persistent SQLite storage, it holds
+ * messages and metadata solely for UI rendering, ensuring responsive scrolling and
+ * display without exceeding ncurses pad limits (10k lines). By tracking rendered
+ * line counts per entry, it proactively trims content to prevent overflow, enabling
+ * seamless integration with ncurses for position-aware rendering.
+ *
+ * Key features and operations:
+ *   - Append/prepend entries (messages) with automatic line-based cleanup.
+ *   - Track cumulative lines for overflow prevention and efficient buffer sizing.
+ *   - Remove entries by ID or index; mark delivery receipts as received.
+ *   - Retrieve entries by index or ID for rendering and history queries.
+ *   - Store metadata including timestamps, senders, themes, and ncurses y-positions.
+ *
+ * CProof. Fork of Profanity (since 2025).
