Merge broker-rugnux-live into rc176: rugnux in jfjoch_broker as a live thread during a DECTRIS rotation collection (off by default), the rugnux library without file I/O (results in ProcessResult::outputs, the CLI writes them through JFJochRugnuxOutput), END carrying the merged table, map coefficients and placed model

Branch reviewed at e16db07ff (review: owner's decisions accepted - _maps.mtz instead of .ccp4 in the
viewer, -o "" computes everything incl. MR/validation, Ctrl+C/error paths may leave fewer files, the
writer links gemmi/zlib) and merged at 55184eb09 with its review fixes (END size guard, frame drop as
in Lite, outputs released before re-runs, pool priority, docs, frontend gating).

Conflicts: rugnux/Rugnux.h (kept rc176's host_memory_budget_bytes, output_prefix removed as on the
branch), rugnux/RugnuxPipeline.h (MtzTable future + rc176's GPUMerge pointer), MolecularReplacement.h/.cpp
(rc176's GPU cost model, packed transform and split functions with the branch's RugnuxModel signature;
search_model with rc176's other_budgets, result.model_name). tests/RugnuxLargeTest.cpp: rc176's
host-budget test writes its files through WriteRugnuxOutputs now that the library writes none.
Generated code (broker/gen, frontend client, Python client docs, Redoc) regenerated from the merged
jfjoch_api.yaml with update_version.sh (version unchanged).
