Introduces `RtlDocEntry` and `RtlRegistration` structs to store and manage documentation for native functions and constants. The `Environment` struct is updated to include a registry for these documentation entries. The `register_native_fn` and `register_constant` methods now return an `RtlRegistration` builder, allowing for optional chaining of `.doc()`, `.description()`, and `.examples()` methods before the registration is finalized when the builder is dropped. Macros `rtl_fn!` and `rtl_const!` are introduced to simplify the registration process with documentation. The MCP server is extended with `get_rtl_docs` and `get_symbol_doc` tools to expose this documentation externally. Specific RTL functions and constants (e.g., `+`, `-`, `*`, `/`, `NaN`, `true`, `false`, `date`, `now`, math functions, `series`, `push`, `len`, `create-random-ohlc`, `create-ticker`, `pipe`) have been updated to include their respective documentation using the new infrastructure. The `Signature` and `StaticType` types have gained `to_doc_string` methods for generating human-readable documentation strings.
