feat!: generic Ring[T] core + RingBuffer byte wrapper, Go 1.23 modern…

[yuikns]

…ization

BREAKING CHANGES:

• Introduce generic core type Ring[T any]
• RingBuffer becomes a byte-specific wrapper around *Ring[byte]
• Byte-specific methods (WriteString, ReadFrom, WriteTo, Copy, Pipe) remain on *RingBuffer for full io compatibility
• Requires Go 1.23+

FEATURES:

• Add All() returning iter.Seq[T] (Go 1.23 iterators)
• Add NewRing[T], NewRingFromSlice[T] constructors
• RingBuffer fully preserves original API including io.ByteReader, io.ByteWriter, io.ReaderFrom, io.WriterTo, io.StringWriter

FIXES:

• Fix goroutine leak in WithCancel using done channel + sync.Once
• Modernize unsafe string-to-bytes conversion in WriteString
• Use builtin min/max and clear() for cleaner code

INFRA:

• Update module path to github.com/argcv/ringbuffer
• Update CI to Go 1.23 and latest action versions
• Remove legacy .travis.yml
• Rewrite README with new API docs
