Crate umsh_text 

Text-message support for UMSH.

This crate implements the stateful text-message protocol once, for use by both mobile applications and embedded pagers:

• codec: exact wire bytes — borrowed decoding and encoding, with extension options preserved for profile-specific validation. Works without alloc.
• validate: semantic validation of a decoded message in conversation context, selected by a validate::TextProfile.
• engine: a deterministic sans-I/O reducer owning sequence allocation, deduplication, fragmentation, reassembly, and bounded repair. It receives commands and emits effects and events; platform code owns presentation, storage, and transports.
• Node-layer convenience wrappers (feature node) for chat-style applications built directly on umsh-node.
