In scope of tarantool/tarantool#8147, a new context-dependent extension for box tuples, `MP_TUPLE`, is introduced. If the merger's buffer source is used, raw MsgPack is received, which does not allow for passing the context required for decoding `MP_TUPLE`. At the same time, all box tuples are now encoded as `MP_TUPLE` by default. If the merger's tuple chunk can be decoded by manually skipping the extension header of `MP_TUPLE` and the tuple format of individual tuples, the cursor is decoded using the Lua `msgpack` library, which cannot handle `MP_TUPLE`s without a decoding context. The cursor's `after_tuple` field is a box tuple, so in order to overcome the limitation above, we need to explicitly convert it to a Lua table. Needed for tarantool/tarantool#8147

Overview This release improves experience for VShard clusters users and Tarantool 3 users. It also introduces schema introspection API. New features * Space schema introspection API `crud.schema` (#380). Bugfixes * Return explicit error for `*_many` call with no tuples/objects (#377). * `crud.readview` resource cleanup on garbage collect (#379). * VShard storage user have not execution rights for internal functions (#366). * Compatibility with Tarantool 3.0 tuple objects (#387). Infrastructure * `deps.sh` installs the `vshard` instead of the `cartridge` by default (#364). You could to specify an environment variable `CARTIRDGE_VERSION` to install the `cartridge` and run tests cases with it. * `doc/playground.lua` does not work with Tarantool 3 (#371). * Tests with Tarantool 3 (#364). * Quickstart section in the README.md focuses on usage with `vshard` instead of `Cartridge` (#366).
