In `@src/lib/fcitx/event.cpp`:
- Around line 41-66: The KeyEventBase::check matching path must preserve Shift
for modifier-sensitive shortcuts such as Control|Shift or Alt|Shift. Update the
relevant caller or mode selection for MatchAllNormalizedKeys so shortcuts
requiring Shift use MatchRawKey, reusing rawKey_ comparison without
normalization while leaving ordinary normalized matching unchanged.
In `@test/testkeyevent.cpp`:
- Line 17: Add regression cases alongside the existing KeyEvent construction to
cover Cyrillic, Greek final sigma, Georgian, and a directly encoded Cherokee
keysym. For each non-Latin keysym, assert that Shift-only input removes Shift
while Control+Shift and Alt+Shift retain it; treat comparisons as exact keysym
checks, not Unicode case-folding.

Use raw-key matching for modifier-preserving shortcuts. For Key(FcitxKey_Arabic_alef, Control|Shift) or Alt|Shift, normalization removes Shift. MatchAllNormalizedKeys then compares only the normalized event values against the configured key, so the shortcut does not match. Use MatchRawKey for shortcuts that require Shift preservation. MatchRawKey already compares rawKey_ without normalization.

Add non-Latin Shift-normalization regression cases.
This test only uses ASCII symbols. Add Cyrillic, Greek final sigma, Georgian, and a directly encoded Cherokee keysym. Assert that Shift-only input removes Shift, while Control+Shift and Alt+Shift retain Shift.
These tests cover Unicode key-symbol normalization. Do not describe them as Unicode case-folding tests because Key::check() compares keysyms exactly.

For global addon, it's more preferable to match system layout instead of
matching the only the post layout convertion.
Also, key code based handling is prefer to match against normalization,
because normalization may remove shift mask and make matching fail.
