feat(adaptive): add bounded algorithm scout

[thinksyncs]

Summary

• Add a bounded, read-only algorithm scout for official release metadata.
• Keep discovered candidates outside the selectable bundle registry.

Changes

• Add a reusable credential-free HTTPS transport with address, redirect, size, timeout, and content limits.
• Add bounded HTML, JSON, and isolated PDF intake with dated checksum-managed reports.
• Add the Experimental scout-algorithms CLI, schemas, manifests, documentation, and generated references.
• Extend CI, package inventory, schema governance, and offline boundary tests.

Testing

• bash scripts/pre_push.sh
• /tmp/yolozu-mcp-test.ONVMiv/venv/bin/python -m unittest tests.test_candidate_artifact_ai_surface -v
• Live smoke against the four canonical official GitHub release endpoints; output remained in a temporary workspace.

Notes

• Default operation is network-free and write-free. Collection requires --collect.
• Scout reports are inbox-only metadata and cannot qualify, register, recommend, execute, or promote a model.
• Traffic collected during the live smoke is interoperability evidence only, not support, quality, or adoption evidence.
