fix: disable cache for synthetic dev/preview commands (#588)

Update SyntheticPlanRequest to use new cache_config field from vite-task.
Synthetic dev and preview commands now explicitly use
UserCacheConfig::disabled() so they are never cached, even when
cacheScripts is enabled.

- Bump vite-task to 9338d15d (adds cache_config to SyntheticPlanRequest)
- Use UserCacheConfig::with_config/disabled helpers for all subcommands
- Add rustc-hash dep for FxHashMap compatibility with vite-task
- Add snap tests validating cache disabled behavior for synthetic commands
