fix(scripts): replace bare except clauses with specific exception types (#77)

Replace 30+ bare `except:` and `except: pass` patterns across 17 files
with specific exception types (OSError, ValueError, etc.) and add
logging so errors are no longer silently swallowed.

Changes by category:

Infrastructure (surface/main.py):
- GPU/process probes now catch FileNotFoundError | SubprocessError

Application scripts:
- API fetchers (finalize_database, final_push, bulk_10x) now catch
  URLError | JSONDecodeError | KeyError | OSError and print to stderr
- Hardware probes (unified_hardware_surface, swarm_transport_layer)
  catch OSError | ValueError for /proc/meminfo reads
- Backend availability checks (prover_backend_interface, hot_swap_manager)
  catch requests.RequestException and log at debug/warning
- Code inspector (swarm_system_inspector) catches OSError | UnicodeDecodeError
  for file reads
- Model fallback (map_all_equations) now logs the intermediate error
- Minor: gpu_pist_compress → RuntimeError | ZeroDivisionError,
  mathlib_to_parquet → ValueError, moe_utils → OSError,
  quandela_remote → OSError | IndexError, topology inline scripts
  → ImportError, consolidate_language_databases → UnicodeDecodeError

All touched files pass py_compile.
