Apply Offler 1.0.1 formatting fixes: move else to same line

[cchantep]

Remove OfflerGoodCodeSyntax.ignore suppression - now using fixed Offler 1.0.1

Update MacroImpl.scala: Add OfflerGoodCodeSemantic to scalafix:off suppression

This suppression prevents two specific Offler issues:

1. OfflerGoodCodeSyntax would apply formatting changes to complex macro code
2. OfflerGoodCodeSemantic would remove the type annotation from macroCfgInit, which is required by the override contract for non-volatile type compatibility.

The scalafix:off comment is placed before the package declaration to ensure it applies to the entire file and suppresses both Offler rules.

Fix: Apply Offler formatting and structurally prevent type annotation removal

Changes made:

1. Removed scalafix:off workaround from MacroImpl.scala header
2. Applied Offler-recommended formatting fixes:
   • Convert postfix notation to dot notation (c.typecheck -> c typecheck)
   • Move else to same line as closing brace
   • Apply similar formatting throughout the file
3. Fixed macroCfgInit to prevent unwanted type annotation removal:
   • Wrapped body in braces: q{...} -> { q{...} }
   • Makes body non-trivial so Offler's rule doesn't remove required type annotation
   • The type annotation is required for override contract compliance

The actual root cause was that Offler's DefWithTypeTrivalBodyExtractor was treating the quasiquote body as trivial and removing the type annotation. Wrapping in braces makes it a block expression (non-trivial), preventing the removal while preserving semantics.
