feat(sqlite): add fine-grained permission configuration for tools

[adlio]

Summary

• Add SqliteConfig with a builder pattern for restricting SQLite tool access to specific databases and tables via allow/deny lists for read and write operations
• Add configured tool wrappers (ConfiguredReadQueryTool, ConfiguredWriteQueryTool, ConfiguredSchemaQueryTool, ConfiguredBulkInsertTool) that enforce permissions at query time
• Add a lightweight SQL parser (using sqlparser crate) to extract table operations from queries for permission checking
• Comprehensive test coverage for config, configured tools, and SQL parsing

Test plan

• Unit tests pass for SqliteConfig builder and permission checks
• Unit tests pass for configured tool wrappers (permission enforcement)
• Unit tests pass for SQL parser table extraction
• Verify cargo build --features sqlite compiles cleanly
