Replace the eager PyJulia/PyCall initialization at import time with a lazy bridge (Modules/JuliaExt.py). The Julia runtime now boots at the first actual use of MODE_FAST_JULIA instead of at "import tdscha", and the backend is juliacall (PythonCall.jl), which has no libpython coupling: no python-jl, no PyCall rebuilds, and Julia is installed automatically on fresh machines through the shipped juliapkg.json. - Remove the triplicated eager init blocks in DynamicalLanczos.py and the one in QSpaceLanczos.py; route all julia.Main call sites through the JuliaExt proxy (numpy <-> Julia Array conversions preserve PyJulia call semantics with the strictly-typed kernel signatures). - is_julia_enabled() / __JULIA_EXT__ keep their meaning (backend availability) without booting the runtime. - Default to a single Julia thread (as PyJulia did): the Threads.@threads kernels in tdscha_core.jl race on shared buffers with >1 thread (see julia_design.md section 7). - New optional extra: pip install tdscha[julia] -> juliacall. - SSCHA_JULIA_BACKEND env var: juliacall | pyjulia (legacy) | none. - Design and measurements documented in julia_design.md; docs updated. A companion patch with the same bridge is needed in python-sscha (sscha.Ensemble had the same eager pattern, worth 194s of the total). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- Bump version in pyproject.toml and meson.build from 1.6.3 to 1.7.0 - Add Examples/ensemble_gold/ (50-config converged SSCHA ensemble, 3x3x3 gold supercell) for non-TRI q-point testing
