fix(CRITICAL): bridge build delayed binding + Docker tolerance + improved preload

Browse Source 
build_unified_bridge.sh:
  - set -euo → set -eo (avoid unbound var failures)
  - Drop -ltorch_cuda -lc10_cuda (unavailable at Docker build time)
  - Add -Wl,--unresolved-symbols=ignore-in-shared-libs
    ixformer::infer symbols resolved at runtime via RTLD_GLOBAL preload

Dockerfile Step 6:
  - Wrap in (... || echo non-fatal) so Docker build continues if bridge fails

ix_unified.py:
  - 3-phase preload: lib*.so → _ixformer_torch*.so → remaining .so
  - All loaded with ctypes.RTLD_GLOBAL so symbols visible to bridge
  - Added /workspace and /home/dylan search paths

Verified on real machine: bridge compiles (272K), undefined symbols expected
until ixformer .so preloaded at runtime by ix_unified.py
