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 ✓

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

针对不同类型的策略，增加不同的sender/receiver个数检查。
...
- is_multi_producer：sender无限制；否则仅允许一个
- is_multi_consumer：receiver个数上限依赖is_broadcast指定；否则仅允许一个
- is_broadcast：receiver个数上限为32（uint_t<32>位数）；否则无限制（uint_t<32>大小）
行为变更：
1. 在连接时根据模式检查sender/receiver是否超出上限，超出则返回false
2. 在send时确认是否允许发送（对receiver模式来说，send之前不会尝试确认sender个数）
3. 修正若干bug
