de76cf80d5 fix(buffer): remove const from char constructor to prevent UB
- Change: explicit buffer(char const & c) → explicit buffer(char & c)
- Remove dangerous const_cast in implementation
- Before: buffer(const_cast<char*>(&c), 1) [UB if c is truly const]
- After: buffer(&c, 1) [safe, requires non-const char]
- Prevents undefined behavior from modifying compile-time constants
- Constructor now correctly requires mutable char reference
- Aligns with buffer's mutable data semantics

The previous implementation with const_cast could lead to:
- Modifying string literals (undefined behavior)
- Modifying const variables (undefined behavior)
- Runtime crashes or data corruption

Example of prevented misuse:
  buffer buf('X');           // Now: compile error ✓
  char c = 'X';
  buffer buf(c);             // Now: works correctly ✓
  const char cc = 'Y';
  buffer buf(cc);            // Now: compile error ✓

8103c117f1 fix(buffer): remove redundant const qualifier in array constructor
- Change: byte_t const (& data)[N] → byte_t (& data)[N]
- Allows non-const byte arrays to be accepted by the constructor
- Fixes defect discovered by TEST_F(BufferTest, ConstructorFromByteArray)
- The const qualifier on array elements was too restrictive
- Keep char const & c unchanged as it's correct for single char reference
