Feat: Config-driven REST API tool registration via YAML (adapter_type: rest_api)

[man4ish]

Summary

Currently adding a new REST-backed tool requires:

• Creating a new Python handler file
• Manual registration in init.py
• YAML config entry

This is not scalable for 100+ tools.

Proposed Solution

Implement config-driven tool registration:

• New adapter_type: rest_api in tools.yaml
• Generic RestApiHandler reads config and executes any REST tool
• Auto-registration via load_tools_from_yaml()
• No Python code needed per tool

Benefits

• Add 100+ tools via YAML only
• Zero code changes per tool
• Consistent validation and execution
• Easy to maintain and extend

Tools to add in first batch

• UniProt Search
• Ensembl Gene Lookup
• PubMed Search
• ClinVar Search
• STRING DB
• KEGG Pathway
• DisGeNET

Acceptance Criteria

• RestApiHandler implemented
• Auto-registration working
• 7 tools added via YAML only
• All tools tested end-to-end
• Documentation updated
• Unit tests added
