Summary

• remove todo tool/runtime support from V1 and V2, including schemas, events, permissions, prompts, routes, and plugin compatibility
• remove todo rendering and state from the CLI, App, TUI, shared UI, web shares, Storybook, and documentation
• remove todo contracts from generated SDK/OpenAPI surfaces and add a migration that drops the persisted todo table

Validation

• bun turbo typecheck --concurrency=3
• bun run test in packages/core (1240 passed)
• affected V1 tests in packages/opencode (361 passed, 1 skipped)
• bun test in packages/schema
• bun run test in packages/sdk/js, packages/cli, packages/session-ui, and packages/ui
• bun run build in packages/web
• bun run migration --check in packages/core
• bun run check:generated in packages/client
• exact todo feature-symbol and endpoint grep returns no matches

The broad V1 and plugin suites still report pre-existing unrelated failures in plugin contract identity, CLI subprocess/runtime timing, and apply-patch rendering.
