Hide generated catalog runtime files

[tannerlinsley]

Summary

• keep generated catalog bootstrap files in the runnable workspace while hiding them from the editor, tabs, and file tree
• preserve hidden-file metadata when examples are shared
• validate hidden paths and prevent them from becoming the initial file

This complements TanStack/charts#102, whose catalog entries now expose only authored case-local source.

Verification

• pnpm test: 191 passed, 1 skipped
• TypeScript and Oxlint passed
• formatting passed

Summary by CodeRabbit

• New Features

  • Added support for hiding internal workspace files from shared project metadata and file lists.
  • Hidden files are excluded from initial-file selection, with visible workspace files preferred as the fallback.
  • Hidden file settings are preserved when projects are created, saved, loaded, and converted.

• Bug Fixes

  • Generated example workspaces now keep catalog and entry files hidden from users.

• Tests

  • Added validation for hidden file persistence, workspace membership, and initial-file restrictions.

📝 Walkthrough

Walkthrough

The change adds optional hidden-file metadata to example definitions and shared projects. Parsing validates hidden paths. The workbench excludes hidden files from its list and initial-file selection. Chart catalog definitions hide generated files.

Changes

Hidden file metadata support

Layer / File(s)	Summary
Hidden file metadata contract and validation src/utils/example-workspace.ts, src/utils/example-project.ts, tests/example-workspace.test.ts	Example definitions and shared projects now preserve hidden file paths. Parsing validates canonical, unique paths that exist in the workspace and do not match initialFile.
Workbench visibility and catalog integration src/components/examples/ExampleWorkbench.client.tsx, src/utils/charts-catalog-example.ts, tests/charts-catalog-example.test.ts	The workbench hides configured files from its list and initial-file selection. Chart catalog definitions hide /__catalog.tsx and /index.html.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to f681c

The workbench can still open a hidden generated file when no visible text file exists, and sharing that state can produce an invalid initial file that readers reject. The PR is not merge-ready until this fallback is removed or the no-visible-file case is handled explicitly and covered by a regression test.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Do not fall back to a hidden workspace.entry.

When no visible text file exists, find(...) returns undefined, so this expression returns workspace.entry even when definition.hiddenFiles contains that path. The workbench then opens a hidden file. Sharing can serialize that path as initialFile, which parseSharedExampleProject rejects. Reject definitions with no visible file or handle that state explicitly before using workspace.entry. Add a regression test for a hidden entry with no visible initial file.
