feat(pgsql): native backend message framer with partial-message handling + unit tests

Add PgSQL_Backend_Msg_Framer: a pure wire-message framer for the native
PostgreSQL backend protocol. It accepts fed bytes (possibly partial) and
yields complete messages (type byte + 4-byte big-endian length-prefixed
body), signaling FRAME_NEED_MORE on incomplete trailing bytes and
FRAME_ERROR on a malformed length. Header stays light (cstdint/cstddef
only). Destructor frees the realloc'd buffer to avoid a leak on
long-lived connections.

Wire it into libproxysql.a via _OBJ_CXX in lib/Makefile.

Also fix a pre-existing duplicate vec.o on the unit-test link line: the
test/tap/tests/unit/Makefile appended SQLITE3_LDIR/vec.o to STATIC_LIBS
in two separate PROXYSQL40 blocks, producing ~98 duplicate-symbol errors
that broke every unit test under PROXYSQL40. Keep the single append after
the autodetection block.
