Merge master into feat/sdk-codegen-b4-qt-host-repoint

Only flake.lock conflicted; flake.nix merged clean. Resolved by regenerating
the lock from the merged flake.nix rather than hand-splicing it.

master's b960f44 bumped logos-view-module-runtime, and this branch rev-pins it
so view-interface-abi compares the B4 templates against the matching B4 host
headers. Keeping the old B4 pin would have walked that bump backward and lost
the hot-reload fix (#24), so the runtime's B4 branch absorbed master first
(logos-view-module-runtime 3ef779c, a clean merge) and this pins that instead.

KNOWN, NOT FIXED HERE: the same bump also moved logos-standalone-app, and this
branch still pins 39f4f2b against master's e582e6c. That one is not a clean
merge — flake.nix, flake.lock and nix/app.nix all conflict — so absorbing it is
its own change. Until then, merging this branch walks the standalone-app pin
back three commits (the hot-reload fix #36 and the capability-startup removal).

view-interface-abi passes against the new runtime pin with no overrides.
