Validated MSA-reuse screen; bump cache_msa timeout for slow MSA server
2-drug confirm passes: MSA cached once + reused, a3m parses (null-strip +
FASTA-selection fix works), screened 2/2, results sensible. The earlier
'screened 0' (a3m KeyError '\x00') and FunctionTimeout (ColabFold server
queued >30min) are both resolved: a3m hardening + cache_msa timeout 4200s.
Corrected screen is end-to-end working: 1 MSA query, reused across all
drugs, exception-tolerant.
