chore(deps): protocol 303ab08 across all three carriers

Level 3 of the propagation of logos-protocol#74 to logos-logoscore-cli, after
logos-plugin-qt#30 and logos-qt-sdk#46. Lock-only.

THREE inputs are bumped, not one, and that is the point of this level:
logos-protocol, logos-qt-sdk and logos-plugin-qt. Those are exactly the inputs
that CARRY a runtime liblogos_protocol.dylib into this closure. Measured across
all eight non-nix inputs -- cpp-sdk, module-loader, capability-module, module
and package-manager carry none.

This repo declares `inputs.logos-protocol.follows` on logos-cpp-sdk, which is
the one input that does NOT carry a protocol lib, and omits it on qt-sdk and
plugin-qt, which do. So their protocol rev is whatever their own locks say, and
each has to be bumped by hand. Today that is invisible because every rev
coincided; the moment one moves alone this closure holds two protocol libs,
which is the duplicate-runtime condition the one-runtime symbol gate exists to
catch. Worth a follow-up (two `follows` lines) rather than repeating this by
hand next time -- deliberately NOT folded in here, so a red artifact could not
be ambiguous between the bump and a topology change.

THE LOCK STILL SHOWS FOUR PROTOCOL REVS AFTERWARDS AND THAT IS CORRECT. 7 nodes,
4 revs: 303ab08 x3 (the carriers), 42460e5 x2 under default-module-loader and
logos-capability-module, plus two deeper. Lock-node count and closure
composition are different questions, and only the second one ships:

    protocol paths in the built logos-liblogos closure: exactly ONE
    n7yilrs2...-logos-protocol-lib-0.8.0        (the build of 303ab08)

which is the same store path verified in the two levels below to carry the
change (UTF-16 "(any)" x1, old warning x0) where the lib it replaces does not.

`nix flake check`: exit 0, 2 checks, no failures. Status read from nix rather
than from a pipeline -- `nix flake check | tail` reports tail's exit code, which
is always 0, and that misreported a check earlier in this chain.
