fix: misplaced doc comment and section numbering after refactor

[Copilot]

Two cosmetic/structural issues introduced by the recent refactoring.

Changes

• src/limiter.c — The Doxygen comment for run_pid_or_exe_mode() was stranded between run_command_mode() and the static helper report_process_not_found(), leaving run_pid_or_exe_mode() with no comment at its definition site. Moved it directly above the function it documents.

  Before:

  } /* end run_command_mode */
  
  /** @brief Search for and limit an existing process ... */  ← wrong position
  
  /** @brief Report that the target process could not be found. */
  static void report_process_not_found(...) { ... }
  
  void run_pid_or_exe_mode(...) { ... }  ← no comment here

  After: report_process_not_found comment stays, run_pid_or_exe_mode comment moves to sit directly above it.

• cmake/CpulimitOptions.cmake — Section headers were numbered 1, 3, 4, 5 (section 2 was removed during refactoring without renumbering the rest). Corrected to 1, 2, 3, 4.
