This PR adds the ability to configure which files are considered
"hidden" in the project panel and toggle their visibility with a
keyboard shortcut. Previously, the editor hardcoded dotfiles as hidden -
now users can customize the pattern and quickly show/hide them.
### Release Notes
- Added `project_panel::ToggleHideHidden` action with keyboard shortcuts
to toggle visibility of hidden files
- Added configurable `hidden_files` setting to customize which files are
marked as hidden (defaults to `**/.*` for dotfiles)
### Motivation
This change allows users to:
1. Quickly toggle hidden file visibility with a keyboard shortcut
2. Customize which files are considered "hidden" beyond just dotfiles
3. Better organize their project panel by hiding build artifacts, logs,
or other generated files
### Usage
**Toggle hidden files:**
- **macOS:** `cmd-alt-.`
- **Linux:** `ctrl-alt-.`
- **Windows:** `ctrl-alt-.`
**Customize patterns in settings:**
```json
{
"hidden_files": ["**/.*", "**/*.tmp", "**/build/**"]
}
```
### Changes
**Core Implementation:**
- Added `hidden_files` setting (defaults to `**/.*` to match current
dotfile behavior)
- Replaced hardcoded `name.starts_with('.')` logic with configurable
pattern matching using `PathMatcher`
- Hidden status propagates through directory hierarchies (if a directory
is hidden, all children inherit that status)
**User-Facing:**
- Added `ToggleHideHidden` action in the project panel
- Added keyboard shortcuts for all platforms
- Added settings UI entry for configuring `hidden_files` patterns
**Testing:**
- Added comprehensive test coverage validating default behavior, custom
patterns, propagation, and settings changes
### Implementation Notes
- Uses `PathMatcher` for efficient glob matching
- Settings changes automatically trigger worktree re-indexing
- No breaking changes - defaults maintain current behavior (hiding
dotfiles)
---
**Disclaimer:** This was implemented with a fair amount of copy/paste
(particularly the gitignore handling), trial and error, and a healthy
dose of Claude.

Release Notes:
- Added the ability to configure glob patterns for files treated as
hidden in the project panel using the `hidden_files` setting.
- Added an action `project panel: toggle hidden files` to quickly show
or hide hidden files in the project panel.
