Subject: [PATCH 22/28] fix(ted): remove ValueChanged handler that caused
 WordWrap double-toggle
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The wordWrapCheckBox.ValueChanged handler conflicted with the MenuItem's
Action handler. When the Menu dispatches Activate to the MenuItem (Shortcut)
with a binding context, the relay dispatch activates the CheckBox first
(triggering ValueChanged → sets WordWrap=true + saves), then fires Action
(which computes !WordWrap=false + saves). Net result: WordWrap reverts to
false and the config file contains the wrong value.

The fix removes the ValueChanged handler entirely. The Action handler
already correctly toggles Editor.WordWrap, updates the CheckBox, and
calls SaveViewSettings(). This matches the pattern used by the other
View menu checkboxes (Line Numbers, Fold Indicators, ShowTabs, etc.).

Added test ViewMenu_WordWrap_Toggle_Persists_True that:
- Opens View menu via Alt+V (matching real user interaction)
- Clicks Word Wrap menu item
- Asserts Editor.WordWrap == true after toggle
- Asserts config file is created with correct content

The test fails without the fix (WordWrap reverts to false) and passes
with it.

Subject: [PATCH 23/28] fix(ted): unify config path to ~/.tui, add Load, remove
 ConfigMgr reset
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three bugs fixed:

1. Config path: GetConfigPath() used %APPDATA%\tui on Windows instead of
   ~/.tui (%USERPROFILE%\.tui). Now uses HOME env var with .tui subdirectory
   on all platforms, matching clet config/edit convention.

2. No explicit Load: settings were never read from ted.config.json on
   startup. TedApp constructor read EditorSettings statics which were at
   their C# defaults. Added EditorSettings.Load() that parses the JSON
   file and populates statics. Called from Program.cs before TedApp
   construction.

3. ConfigurationManager.Load+Apply after every save: Save() called
   ConfigurationManager.Load(All) + Apply() which could reset
   EditorSettings statics to defaults, causing cross-setting interference
   (e.g., ShowTabs and WordWrap undoing each other). Removed — the JSON
   file write is sufficient.

Also:
- Made GetConfigPath() internal for testability
- Added InternalsVisibleTo for test project
- Added Load_Reads_Settings_From_ConfigFile test
- Added Load_TedApp_Applies_Persisted_WordWrap test
- Simplified ConfigPathScope (no longer needs APPDATA redirect)

Subject: [PATCH 24/28] fix(ted): prevent IndentSize < 1 via ValueChanging

Use NumericUpDown.ValueChanging to reject values below 1 instead of
clamping after the fact in ApplyTo. The Math.Max(1, ...) guard in
ApplyTo remains as a safety net.

Updated test to verify the rejection behavior.

Subject: [PATCH 25/28] fix(test): reset EditorSettings statics after Load
 tests

Load_Reads_Settings_From_ConfigFile and Load_TedApp_Applies_Persisted_WordWrap
modify EditorSettings static properties (e.g., WordWrap=true) but didn't
restore defaults. On macOS/Linux where test execution order differs from
Windows, this polluted subsequent tests (ViewMenu_WordWrap_Toggle_Persists_True
expected WordWrap=false initially).

Subject: [PATCH 26/28] refactor(test): avoid direct static assertions, reset
 in ConfigPathScope

- Merged Load_Reads_Settings_From_ConfigFile and
  Load_TedApp_Applies_Persisted_WordWrap into a single
  Load_TedApp_Applies_Persisted_Settings test that asserts via
  TedApp.Editor instance properties (not EditorSettings statics)
- Moved EditorSettings statics reset into ConfigPathScope.Dispose so
  every test that uses a scope gets clean static state automatically
- Removed standalone ResetEditorSettingsDefaults helper

Subject: [PATCH 27/28] fix(ted): skip JSONC-commented lines when loading
 settings

ReadBool and ReadInt used unanchored regex that could match keys inside
// comments, loading stale/wrong values from JSONC config files.

Fixed by anchoring to start-of-line with a negative lookahead for
leading //. Added Load_Skips_Commented_Out_Settings test.

Addresses Codex review P2 findings on EditorSettings.cs.

Subject: [PATCH 28/28] fix(ted): harden ReadBool/ReadInt and Save against edge
 cases

- ReadBool/ReadInt: require key at JSON property position (only
  whitespace before quoted key), preventing false matches from keys
  embedded inside string values on the same line.
- Save: use FindRootClosingBrace() that skips any '}' on lines
  starting with '//', preventing insertion into trailing JSONC comments.
- Added regression tests for both scenarios.
