Enable flake8-annotations rules to enforce return type annotations: - ANN201: missing-return-type-undocumented-public-function - ANN202: missing-return-type-private-function - ANN205: missing-return-type-static-method - ANN206: missing-return-type-class-method All existing code already complies with these rules.

…e 4/4) Complete Phase 4 of ANN001 linter rule migration by adding type annotations to all function arguments in the manager package (234 violations fixed). Changes include: - manager/config: ManagerStatus type annotation - manager/data: ColumnElement type annotations - manager/api: GraphQL middleware, utilities, and endpoint handlers - manager/cli: All Click CLI command parameters - manager/api/gql_legacy: GraphQL resolvers, mutations, and utilities Type annotation patterns applied: - GraphQL resolvers: root: Any, info: graphene.ResolveInfo - Mutations: **kwargs: Any with properly typed specific parameters - Click CLI: param: click.Parameter | None, ctx: click.Context | None - Utility functions: Appropriate types based on context Mypy fixes: - gql_relay.py: Fixed type checking for connection_type parameter - routing.py: Handle int | None return type conversion - endpoint.py: Pass required GraphQueryContext, fix return types - artifact db_source: Cast InstrumentedAttribute to ColumnElement - session.py: Convert Mapping to dict for type compatibility This completes all 4 phases of the ANN001 migration: - Phase 1: helpers, install, logging, account_manager, accelerator, common (91 violations) - Phase 2: kernel (121 violations) - Phase 3: agent (139 violations) - Phase 4: manager (234 violations) Total: 585 violations fixed across all modules.

Pull request overview
This PR completes Phase 5 of the ANN001 linter rule migration by adding type annotations to function arguments across the entire codebase. The PR fixes 461 violations in this phase (1046+ total across all phases) and removes the ANN001 rule from the ruff ignore list.
Changes:
- Added type annotations to function arguments in client, web, testutils, appproxy, manager, agent, storage, kernel, and accelerator modules
- Fixed mypy type errors introduced by the new annotations using appropriate casts, type guards, and type ignore comments
- Removed test files that appear to be empty or no longer needed
