Note tiles try to read an undefined file path and fail with ENOENT

[BearHuddleston]

Summary

Creating or opening a note tile causes the app to try to read a file path of undefined, which fails with an ENOENT from the desktop file bridge.

Observed error:

Error: Error invoking remote method 'fs:readfile': Error: ENOENT: no such file or directory, open 'C:\Users\arkouda\AppData\Local\Programs\Collaborator\undefined'

Reproduction

1. Create a note tile via the collab canvas tools/UI.
2. Open or render the tile.
3. The app attempts to read a file path and throws the ENOENT above.

What I observed

• A code tile includes a real filePath in its tile metadata.
• A note tile does not include filePath.
• The failing path resolves exactly like a missing filePath is being passed into the desktop fs:readfile bridge and normalized into the Collaborator app directory.

Expected behavior

note tiles should be treated as in-memory content, or otherwise avoid file reads unless a valid backing path exists.

Likely fix

Guard file-backed tile loading by tile type and reject missing filePath before calling fs:readfile. In particular, note should not flow through the same file-loading path as code/other file-backed tiles.
