build: add cache to ./configure with -C flag

Add the -C flag to ./configure to enable caching, reducing redundant
resource fetching during builds when packages and the machine remain
unchanged. Caching may cause issues only if applied across different machines
or if packages are modified, neither of which is the case during the build.

+ *
+ * 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).
