Implements I4 from NEXT_100_PR_MAP: adapter stub module.

What

• src/openamp_foundry/interop/adapter_stub.py: adapter stub with ADS- prefix
• VALID_TARGET_TOOLS (10): ampscanner, campr3, dbaasp, dramp, hmmer, iamp2l, modlamp, peptide_ranker, propedia, rosetta_fold
• VALID_OUTPUT_FORMATS (6): fasta, csv, json, tsv, pdb_sequence_list, sdf
• VALID_ADAPTER_STATUSES (4): stub, partial, complete, deprecated
• AdapterField (5 fields), AdapterStubRecord (9 fields), AdapterValidationResult
• 10 validation rules: prefix, target_tool, output_format, status, dry_lab_only, disclaimer present, disclaimer mentions biological, version, implementation_notes, field mapping field checks
• STUB_DISCLAIMER enforced; must mention biological activity not implied
• format_adapter_stub_record() with field mapping table
• 63 tests across 4 classes; BASELINE 7906→8158

Why

External labs use AMPScanner, modlamp, DRAMP etc. to validate candidates. An adapter stub with explicit field mappings, version tracking, and dry-lab enforcement means integration work can be reviewed before it creates data provenance gaps.

Disconfirming pass

• dry_lab_only=False blocked
• disclaimer without 'biological' blocked
• Unknown tools blocked
• Unknown output formats blocked
• Empty field mapping source/target fields blocked
