feat(tasks): run lifecycle script on task creation

[Godzilaa]

• Adds a create-task checkbox to run the configured Run lifecycle script after provisioning.
• Threads runScriptOnCreate through task creation params.
• Starts the existing lifecycle runner in the main process and logs failures without blocking task creation.

Validation passed: pnpm run format:check, pnpm run typecheck, pnpm run lint, pnpm run test

Greptile Summary

This PR adds a "Run script after task creation" toggle to the Create Task modal that fires the project's configured run lifecycle script immediately after a task is provisioned, without blocking task creation on the result.

• src/shared/tasks.ts adds an optional runScriptOnCreate boolean to CreateTaskParams.
• create-task-modal.tsx reads the project's run script setting via getProjectSettingsStore, conditionally renders the Switch, and passes runScriptOnCreate && hasRunScript through all three creation strategies.
• createTask.ts fires runLifecycleScript with void after provisioning and captures any error with a log.warn, ensuring failures do not surface to the user.

Confidence Score: 4/5

Safe to merge; the change is additive and existing guards prevent any unintended script execution.

The implementation is clean and the double guard prevents accidental execution. The trade-off worth noting is that when both the run script and an initial conversation are provided, the script executes concurrently with the agent rather than before it.

src/main/core/tasks/operations/createTask.ts — the ordering of the lifecycle script relative to createConversation is worth a second look for use cases where runScriptOnCreate and initialConversation are both set.

Important Files Changed

Filename	Overview
src/main/core/tasks/operations/createTask.ts	Adds non-blocking lifecycle script invocation after provisioning; workspaceId access is safe, error is caught and logged, but the script races with any initialConversation that is also provided.
src/renderer/features/tasks/create-task-modal/create-task-modal.tsx	Adds runScriptOnCreate switch, gated behind hasRunScript, correctly threaded through all three creation strategies and reset on project change.
src/shared/tasks.ts	Adds optional runScriptOnCreate field to CreateTaskParams; additive, non-breaking change.

   Lifecycle script races with initial conversation

   runLifecycleScript is fired-and-forgotten, then createConversation is await-ed immediately after. When both runScriptOnCreate and initialConversation are set, the AI agent can begin executing commands in the workspace while the run script is still running. If the run script configures the environment (e.g., installs dependencies or starts a service the agent needs), the agent may encounter a partially initialised workspace on startup.

   **Lifecycle script races with initial conversation**
   
   `runLifecycleScript` is fired-and-forgotten, then `createConversation` is `await`-ed immediately after. When both `runScriptOnCreate` and `initialConversation` are set, the AI agent can begin executing commands in the workspace while the `run` script is still running. If the run script configures the environment (e.g., installs dependencies or starts a service the agent needs), the agent may encounter a partially initialised workspace on startup.
