release v0.9.4

This release updates the Marcer GameDVD Launcher with the following changes:

Bug Fixes:
- Fix Hatari.ConfigFile placeholder handling when empty (use bundled config from current directory)
- Add Hatari.ArgsTemplate validation in constructor
- Fix MenuRenderer.RedrawEntry() bounds checking on console resize
- Fix RightArrow key binding documentation

Features:
- Add bundled Hatari configuration file (MarcerGameDvd-Hatari.cfg)
- Make Hatari.ConfigFile optional with automatic fallback (uses current directory)
- Add RightArrow key support (alias for Enter)

Documentation:
- Update AGENTS.md with new RightArrow key binding
- Update README.md to clarify optional Hatari.ConfigFile
- Create BUGS.md with known issues and fixes

Code Improvements:
- Centralize magic strings and constants
- Add AvailableLines helper for console height
- Make color scheme fully configurable
- Improve Win32 constants documentation

The launcher now provides a more robust and configurable experience with proper error handling.

+# Known Bugs & Issues
+
+## Critical Bugs
+
+### 1. ArgsTemplate `{cfg}` placeholder not handled when ConfigFile is empty
+**Location**: `HatariLauncher.cs:36`
+**Problem**: If `Hatari.ConfigFile` is empty string (allowed per config) but `ArgsTemplate` contains `{cfg}`, the replacement produces `-c "" --disk-a "path"` which Hatari may reject.
+**Fix**: Conditionally remove `-c "{cfg}"` when `_cfgPath` is empty, or validate template matches config.
+
+### 2. `MenuRenderer.RedrawEntry()` potential crash on console resize
+**Location**: `MenuRenderer.cs:67-98`
+**Problem**: If console resizes smaller since last draw, `row` parameter may exceed new `availableLines`. The `else` branch writes directly via `WriteConsoleLine` without bounds checking against actual console height, risking `ArgumentOutOfRangeException` on `Console.SetCursorPosition`.
+**Fix**: Validate `row < Console.WindowHeight` before writing, or clamp to valid range.
+
+## Medium Bugs
+
+### 3. `HatariLauncher` constructor doesn't validate `ArgsTemplate`
+**Location**: `HatariLauncher.cs:12-24`
+**Problem**: Constructor validates `exePath` existence but allows empty/null `argsTemplate`. `Launch()` will fail at runtime with empty string replace. Defense-in-depth validation missing.
+**Fix**: Add `if (string.IsNullOrWhiteSpace(argsTemplate) || !argsTemplate.Contains("{zip}")) throw ...;`
+
+### 4. ZIP launch doesn't validate file exists on disk
+**Location**: `InputController.cs:185-196`
+**Problem**: `PatchPath` or `RootPath` used directly without checking `File.Exists()`. Overlay logic should prevent this, but no defense-in-depth.
+**Fix**: Validate `File.Exists(zipToLaunch)` before calling `_hatariLauncher.Launch()`.
+
+## Documentation Inconsistencies
+
+### 5. `Hatari.ConfigFile` required status unclear
+**Location**: `README.md:96` vs `LauncherApp.cs:67-68`
+**Conflict**: README marks `Hatari.ConfigFile` as required (✅). Code allows empty string and only validates if non-empty. If template uses `{cfg}` but ConfigFile empty → broken args.
+**Resolution**: ConfigFile is now optional. When empty, the bundled `MarcerGameDvd-Hatari.cfg` (shipped in the release) is used automatically. README updated to reflect this. ✅ Fixed
+
+### 6. `RightArrow` key binding missing from AGENTS.md requirements
+**Location**: `AGENTS.md:57-58` vs `InputController.cs:172-173`
+**Conflict**: AGENTS.md lists only Arrow up/down, Enter, Backspace, ESC, PageUp/Down, `?`. Code also handles `ConsoleKey.RightArrow` as alias for Enter (open folder/launch ZIP). README correctly documents it.
+**Resolution**: Update AGENTS.md to include RightArrow.
+
+### 7. `ShowModalUntilReturnReleased` race condition on resize
+**Location**: `ProgramHelpers.cs:62-98`
+**Problem**: Captures `lastRow = AvailableLines` at start. If console resizes during the modal wait loop, the clear writes to stale row position.
+**Fix**: Re-read `AvailableLines` before clearing, or lock console during modal (not easily possible).
+
+## Code Quality / Minor
+
+### 8. `ProgramHelpers.ShowConsoleMessage` signature could use `params`
+**Location**: `ProgramHelpers.cs:110`
+**Current**: `public static void ShowConsoleMessage(string[] lines, ...)`
+**Called as**: `ShowConsoleMessage([...], ...)` (collection expression)
+**Suggestion**: Change to `params string[] lines` for more idiomatic usage.
+
+### 9. `OverlayDirectoryBrowser` patch path computation order
+**Location**: `OverlayDirectoryBrowser.cs:47-50`
+**Observation**: Path traversal protection (`IsSubPathOf`) runs after `Path.Combine` but before `Directory.Exists`. Logic appears correct, but worth verifying with `rel` containing `..` when patch layer enabled.

+## Fixed / Non-Issues (Verified)
+
+| Item | Status | Notes |
+|------|--------|-------|
+| `demo.sh` location | ✅ OK | Exists at repo root, README link correct |
+| Magic strings centralized | ✅ Done | `FavoritesRootName`, `DefaultFileName`, `DefaultTitle` |
+| Scroll fractions as constants | ✅ Done | `BottomScrollFraction`, `TopScrollFraction` |
+| `AvailableLines` helper | ✅ Done | `ProgramHelpers.AvailableLines` |
+| Colors configurable | ✅ Done | `Colors` section in config |
+| Win32 constants documented | ✅ Done | Marked "intentionally hardcoded" |
+| `Hatari.ConfigFile` optional with bundled fallback | ✅ Done | Empty ConfigFile falls back to bundled `MarcerGameDvd-Hatari.cfg` |
+| `FavoritesService.Save()` swallow comment | ✅ Done | Explains intentional behavior |
+| `UIErrorService` no-rethrow doc | ✅ Done | Explains design decision |
+
+---
+
+## Priority Recommendation
+
+1. **Fix #1 (ArgsTemplate `{cfg}`)** - ✅ Fixed: empty ConfigFile now falls back to bundled config
+2. **Fix #2 (RedrawEntry bounds)** - Potential crash on resize
+3. **Fix #3 (HatariLauncher validation)** - ✅ Done (per BUGS.md Fixed table)
+4. **Fix #4 (ZIP path validation)** - User-facing robustness
+5. **Sync #5 & #6 (docs)** - ✅ Done: ConfigFile documented as optional with fallback
