fix(web): open project dialog not showing directories

[lxxonx]

Summary

• Fix "Open project" dialog showing "No folders found" in web mode
• Related to Cannot ’open project‘ in Web mode #6307 (closed but fix was incomplete)

Problem

Three issues prevented the Open Project dialog from working:

1. Server: query parameter was required but SDK sends empty string as undefined, causing 400 Bad Request
2. Server: directory parameter was ignored, always searching current project directory instead of home
3. UI: useFilteredList hook didn't properly handle async items function, causing Promise to be used as array

Changes

packages/opencode/src/server/server.ts

• Make query parameter optional with default empty string
• Add directory parameter support to /find/file endpoint
• Implement directory scanning when directory param is provided (2 levels deep)

packages/ui/src/hooks/use-filtered-list.tsx

• Fix createResource source function to not call async functions synchronously
• Properly await async items function in fetcher

packages/app/src/components/dialog-select-directory.tsx

• Add null-safety to filter.trim() call

Testing

Tested locally with opencode web - dialog now shows home directories and search works correctly.

The following comment was made by an LLM, it may be inaccurate:

Based on my search, I found one potentially related PR:

Related PR:

• PR fix(ui): handle async items function in useFilteredList hook #8157: "fix(ui): handle async items function in useFilteredList hook"
  • fix(ui): handle async items function in useFilteredList hook #8157
  • Why it's related: This PR addresses the same useFilteredList async items function issue that is part of the fixes in PR fix(web): open project dialog not showing directories #8186. If fix(ui): handle async items function in useFilteredList hook #8157 is already merged or in progress, it may partially overlap with this PR's changes.

Note: PR #6940 "feat: improve directory search with path completion and subdirectory listing" appeared in search results but is likely a related feature enhancement rather than a duplicate fix.
