2.0.0 (in progress)

Breaking: Rename includeGuardPat to includeGuard.
Breaking: Off-by-default rule added:
- Include guards and #pragma once are no longer handled by default.
- New pragmaOnce setting controls #pragma once handling.
Breaking: Transitional mode in TOML now must be specified as [transitional] instead of [Transitional] to keep it consistent with the command line and project naming convention
Maybe Breaking: moduleInterfaceExt default changed to ".ixx" (from ".cppm") for MSVC compatibility.
New:
- SOFComments setting for handling start-of-file comments (e.g., licenses).
- Minimizer now removes empty #el... statements.
Changes & Fixes:
- Split IncludePrevention test into include guard and #pragma once tests.
- Removed condition generation for local includes in transitional mode.
- Updated descriptions for includeGuard settings.
- Renamed test Other to ModeIndependent.
- Minimizer and umbrella header tests are now ModeIndependent.
- CMake precompiled headers are now optional (opt-in with PCH).
- Switched argument parser to Taywee/Args (avoids std::any issues on Windows Clang #13).

1.1.0

Add a shared directive section in transitional mode to shorten the preamble.
CondMinimizer renamed to Minimizer that will also remove empty #define/#undef pair.
Remove all *Action return from function. Perform the action directly and shorten code with a lambda.
Add umbrella header support, converting includes to export import instead of import.
Bump PCRE2 to 10.45.

Fix includeGuardPat not matching the entire string to qualify as a guard.
Fix CondMinimizer always skipping #if instead of only when its skippable.
Fix raw string handling because the first ( is not skipped over.
Fix integer literals not being handled properly (I didn't think about them at all LOL).
Fix CondMinimizer not handling nested #if (it looks for the earliest #endif) when skipping.
Make condition hierarchy shorter by removing conditions for all imports.
Bump libfmt to 11.1.3, PCRE2 to 10.45-RC1, Argparse to 3.2.
