Release v0.9.7: Security Validation and Connector Contract

[wxai-space]

Summary

• Add a dependency-free ConnectorManifest, offline validator, structured diagnostics, and top-level public APIs for composing existing Tools, Skills, MCP settings, Hooks, memory adapters, optional extras, and documentation.
• Add credential-free local research and enterprise API connector examples, with tests proving validation does not execute components or perform network access.
• Expand Python executor AST hardening for aliases, dynamic dispatch, getattr, attrgetter, __dict__/subscript access, dangerous builtins, nested imports, and safe false-positive cases.
• Expand shared Graph Memory adversarial coverage and add an explicitly opt-in Mem0 Graph backend matrix without overstating the framework mitigation as a complete backend fix.
• Add Connector, Python executor security, shared Graph Memory validation, and v1.0 public API compatibility documentation.
• Bump the package version to v0.9.7 and update the roadmap.

Compatibility

• Existing agent.run("hello"), structured results, streaming, LightFlow, Hooks, Guardrails, review, and memory APIs remain compatible.
• Connector manifests compose existing extension points and do not introduce a parallel plugin runtime.
• Connector validation does not install dependencies, start MCP services, call tools/hooks, or perform default network requests.
• No new required core dependency is introduced.

Security Scope

The tracked fake-backend tests validate LightAgent's framework boundary against destructive shared-memory behavior. The real Mem0 Graph test remains opt-in and must run against the exact isolated backend version and storage configuration before issue #39 can be scoped or closed.

Testing

• Full future-CI suite: 193 passed, 1 skipped
• Skipped: opt-in real Mem0 Graph backend matrix
• python -m compileall -q ... passed
• git diff --check passed
• Wheel build passed: lightagent-0.9.7-py3-none-any.whl
• Wheel metadata verified: Version: 0.9.7, Requires-Python: >=3.10,<4.0
