Subject: [PATCH] feat: extend Bc methods to accept int|float|string inputs
 (closes #1)

  - All Bc scalar methods now accept int|float|string instead of string only
  - Array methods accept array<int|float|string>
  - Added (string) casts before Guard::isNumeric() calls
  - PHPStan @phpstan-ignore-line for bcmath numeric-string constraints
  - Removed redundant @param docblocks (types in signatures, per cs-fixer)
