Module runtime 

Runtime-mode and verbosity primitives. Runtime hint model shared across host, native commands, and plugin boundaries.

This module exists so runtime-facing behavior like verbosity, output mode, and terminal identity can travel through the system as normalized data instead of ad hoc environment parsing in each caller.

High-level flow:

• parse runtime-oriented environment hints into crate::core::runtime::RuntimeHints
• normalize those values into enums and bounded scalar settings
• export the same normalized hints back into environment pairs when needed

Contract:

• environment parsing rules for runtime hints live here
• callers should consume crate::core::runtime::RuntimeHints instead of reparsing raw env vars

Public API shape:

• crate::core::runtime::RuntimeHints::new is the exact constructor for already-resolved runtime settings
• crate::core::runtime::RuntimeHints::from_env and crate::core::runtime::RuntimeHints::from_env_iter are the probing and adaptation factories
• optional metadata such as profile and terminal identity uses with_* refinements instead of raw ad hoc assembly
