Claude Bot e7c624e773 Add missing module polling in watch mode

When a script tries to import a file that doesn't exist in watch mode,
Bun now polls for the missing module instead of exiting with an error.
This allows developers to create the file and have Bun automatically
reload once it appears.

## Implementation

- Created `MissingModulePollTimer.zig` that polls for missing files
  using exponential backoff (2ms to 100ms intervals)
- Added timer integration to EventLoopTimer enum and fire handler
- Integrated polling detection in `VirtualMachine.uncaughtException()`
  and `handlePendingInternalPromiseRejection()`
- Detects MODULE_NOT_FOUND and ERR_MODULE_NOT_FOUND error codes
- Triggers hot reload when the missing file appears

## Testing

Added tests that verify the module polling works correctly when
a missing module is created after the process starts.
