fix(flatfile): harden flat-file backend against injection and traversal attacks

Security fixes for 7 vulnerabilities in database_flatfile.c:

1. Path traversal via crafted JID (HIGH):
   _ff_jid_to_dir() now strips '/', '\' -> '_' and collapses '..' -> '__',
   preventing a malicious federated JID from escaping the log directory.

2. Log injection via unescaped message body (HIGH):
   Add _ff_escape_message()/_ff_unescape_message() -- escape \n, \r, \\
   in message text on write, unescape on read. Prevents remote contacts
   from injecting fake log lines with forged sender/timestamp/encryption.

3. Metadata field injection (HIGH):
   Add _ff_escape_meta_value()/_ff_unescape_meta_value() -- escape |, ],
   \\, \n, \r in stanza_id/archive_id/replace_id. Parser uses escape-aware
   _ff_find_unescaped_char() and _ff_split_meta() instead of strchr/strsplit.

4. Sender ": " parsing confusion (MEDIUM):
   Escape ": " -> "\: " in XMPP resource on write. Parser uses
   _ff_find_unescaped_colonspace() + _ff_unescape_sender_resource().

5. LMC correction chain cycle -> infinite loop (MEDIUM):
   Add visited hash-set and FF_MAX_LMC_DEPTH (100) limit to chain walker.

6. Unbounded getline() -> OOM (MEDIUM):
   Add FF_MAX_LINE_LEN (10 MB) cap in _ff_readline(); overlength lines
   are skipped with a warning. Replaces all char buf[8192]/fgets() sites
   with dynamic getline() + truncated-line detection at EOF.

7. Symlink attack + TOCTOU on file creation (MEDIUM):
   Replace fopen("a") with open(O_WRONLY|O_APPEND|O_CREAT|O_EXCL|O_NOFOLLOW)
   + fdopen() -- atomic new-file detection, symlink rejection via O_NOFOLLOW.
   _ff_ensure_dir() checks g_lstat() for symlinks. File permissions 0600
   set via open() mode, not post-hoc g_chmod().

+0.16.0 (unreleased)
+===================
+
+Changes:
+- Add flat-file database backend as alternative to SQLite for message history.
+  Stores messages as human-readable plain text files. Configure with `/privacy logging flatfile`.
+  Files are stored in ~/.local/share/profanity/flatlog/.
+- Add `/history verify [<jid>]` command to check integrity of stored message
+  history (works with both SQLite and flat-file backends).
+- Add vtable-based database backend abstraction allowing pluggable storage.
+- Add `make check-functional-flatfile` target to run functional tests with
+  flat-file backend.

+
+### 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.

+By default, message history is stored in an SQLite database. An alternative flat-file backend
+stores messages as human-readable plain text files that can be edited with any text editor.

+To enable flat-file logging, set in
+.IR profrc :

+ * 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
+ *   Group 2: Message, Receipts, Roster, Chat Session
+ *   Group 3: Presence, Disconnect
+ *   Group 4: MUC, Carbons
+ *
+ * Parallel execution:
+ *   ./functionaltests        - run all tests sequentially
+ *   ./functionaltests N      - run group N only (N = 1..num_groups)
+ *
+ * For parallel execution, run multiple groups simultaneously:
