Bring the shared backend contract and TIPC plan in line with
current runtime behavior and downstream implementation evidence.
Rework the QUIC plan around actor-owned endpoint, bootstrap,
stream, listener and cleanup lifecycles, with explicit validation
gates for the still-unverified UniFFI details.

Landing page for `ai/tpt-backends/`: points at the contract spec
as required first reading, tables the 3 plans against their
issues/deps/size, and states the landing order + why.
Deats,
- TIPC first as the cheap proof the table-registration story
generalizes to a genuinely new proto (stdlib-only, and
`trio`'s sock wrappers are family-agnostic).
- `wg` layer-A next since it's deployable-today doc/example work.
- QUIC last, gated on its own prep PR.
- notes that plans 01 and 02 both want the same
`Address.rebind_from_sockname` gate, so whichever lands first
ships it.
