tests: add functional tests for DB message persistence, rebalance groups

Add backend-agnostic functional tests for database message persistence. All tests work with both SQLite and flat-file backends. New tests in test_history.c: - message_db_history_on_reopen: basic incoming write+read round-trip - message_db_history_multiple: 3 messages from different resources - message_db_history_contact_isolation: buddy1 msg absent from buddy2 - message_db_history_special_chars: XML entities survive decode+DB - message_db_history_outgoing: sent message persists across reopen - message_db_history_dialog: outgoing + incoming both in history - message_db_history_empty: no crash on contact with no history - message_db_history_long_message: 1000+ char body not truncated - message_db_history_newline: embedded LF stored correctly - message_db_history_service_chars: backslash pipe percent braces etc - message_db_history_verify: /history verify (ifdef HAVE_HISTORY_VERIFY) - message_db_history_lmc: XEP-0308 correction replaces original in DB Rebalance test groups for parallel execution (19/22/22/21): - Group 1: Connect, Ping, Rooms, Software, LastActivity - Group 2: Message, Receipts, Roster, DB History - Group 3: Chat Session, Presence, Disconnect - Group 4: MUC, Carbons

 This will run the same tests that the CI runs and refuse the push if it fails.
+The CI script runs 4 parallel builds with different configurations:
+- **Full** — all features enabled (+ coverage in `--coverage-only` mode)
+- **Minimal** — all optional features disabled
+- **NoEncrypt** — no encryption (OTR, PGP, OMEMO disabled)
+- **Default** — default ./configure options
+
+Each build runs Valgrind and functional tests on Linux.
+Use `./ci-build.sh --coverage-only` to run only the Full build with coverage collection.
+
+Output shows test results per build:
+```

+  Unit tests:       437 passed, 0 failed
+  Functional tests: 69 passed, 0 failed

+### Security checks
+
+We have a static analyzer `check-cwe134.sh` that detects CWE-134 format string vulnerabilities. It runs automatically in CI but you can also run it locally:
+
+```bash
+./check-cwe134.sh
+```
+
+This checks for unsafe patterns where data could be passed directly as a format string to functions like `printf`, `cons_show`, etc. Never pass a raw string for formatting; use `"%s"` format specifier instead.
+
 ### Finding typos

 We include a `.codespellrc` configuration file for `codespell` in the root directory.
@@ -137,3 +165,55 @@ You can run the `make spell` command for this.

 `make doublecheck` will run the code formatter, spell checker and unit tests.

+
+### Functional tests
+
+The functional test suite uses [stabber](https://git.jabber.space/devs/stabber) as a mock XMPP server. Tests are located in `tests/functionaltests/`.
+
+#### Running functional tests
+
+Functional tests require stabber to be installed. Once installed, tests run as part of `make check`:
+
+```bash
+make check                      # Run all tests (unit + functional)
+make check-functional-parallel  # Run functional tests in parallel (~3x faster)
+./tests/functionaltests/functionaltests    # Run all functional tests sequentially
+./tests/functionaltests/functionaltests 1  # Run specific group (1-4)
+```
+
+#### Test groups
+
+Tests are organized into 4 groups for parallel execution:
+
+| Group | Description |
+|-------|-------------|
+| 1 | Connect, Ping, Rooms, Software |
+| 2 | Message, Receipts, Roster, Chat Session |
+| 3 | Presence, Disconnect |
+| 4 | MUC, Carbons |
+
+To add a new group:
+1. Define the test array in `functionaltests.c`
+2. Add entry to `groups[]` array
+3. Update `FUNC_TEST_GROUPS` in `Makefile.am`
+
+#### Writing functional tests
+
+Use content-based stubbing with stabber:
+
+```c
+// Use stbbr_for_query for IQ queries (roster, disco, etc.)
+stbbr_for_query("jabber:iq:roster", "<iq type='result'>...</iq>");
+
+// Use stbbr_send for presence, message, and push-style stanzas
+stbbr_send("<presence from='buddy@localhost'>...</presence>");
+```
+
+Guidelines:
+
+1. Use `stbbr_for_query(namespace, xml)` for IQ queries where the namespace is stable.
+2. Use `stbbr_send(xml)` for presence, message, and other push-style stanzas.
+3. Keep assertions tolerant of ordering when possible; use `prof_output_regex()` for flexible matching.
+4. If timing issues appear, use `prof_timeout()` around critical expectations and reset afterwards.
+5. When adding new tests, place them in the appropriate group based on functionality.

+ * 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.

+ * Functional tests for CProof XMPP client.
+ * Uses cmocka framework with stabber mock XMPP server.
+ *
+ * Each test is wrapped with PROF_FUNC_TEST macro which sets up
+ * init_prof_test (starts stabber server and profanity client)
+ * and close_prof_test (cleanup) as setup/teardown functions.
+ *
+ * NOTE: We restart client and server for each test to ensure complete
+ * isolation. This prevents state leakage between tests (roster entries,
+ * MUC rooms, presence subscriptions, etc.). While slower, it eliminates
+ * flaky tests caused by leftover state. The overhead is acceptable since
+ * functional tests run less frequently than unit tests.
+ *
+ * Tests are organized into groups for better maintainability and parallel execution:
+ *   Group 1: Connect, Ping, Rooms, Software, Last Activity  (19 tests)
+ *   Group 2: Message, Receipts, Roster, DB History           (22 tests)
+ *   Group 3: Chat Session, Presence, Disconnect              (22 tests)
+ *   Group 4: MUC, Carbons                                    (21 tests)
+ *
+ * Parallel execution:
+ *   ./functionaltests        - run all tests sequentially
+ *   ./functionaltests N      - run group N only (N = 1..num_groups)
+ *
+ * For parallel execution, run multiple groups simultaneously:
