fix(search): include restored files in global search

[bajrangCoder]

Fixes: #2825

[greptile-apps]

Greptile Summary

The PR prevents unloaded restored-file placeholders from overriding filesystem content during global search.

• Requires an editor file to be fully loaded before worker-based search reads its document.
• Applies the same loaded-state filtering to native-search overlays.

Confidence Score: 4/5

The remote-file loading race should be fixed before merging because global search can temporarily ignore recovered unsaved content.

The new worker-path guard falls back to remote source content during an observable interval when the editor session already contains authoritative recovery text but has not yet been marked loaded.

Important Files Changed

Filename	Overview
src/sidebarApps/searchInFiles/index.js	Adds loaded-state guards to both search-content paths, but the worker guard can temporarily discard authoritative recovery text for asynchronously loading remote files.
