Shared JSONC comment stripping utility.

Supports:

• // line comments
• /* ... */ block comments
• string literal preservation (including escapes)

zpl_toolchain_jsonc_strip

Shared JSONC comment stripping utility used by multiple build-time tooling paths.

Purpose

Provides a single strip_jsonc() implementation to prevent drift between:

• crates/spec-compiler
• crates/diagnostics build script

Guarantees

• strips // line comments
• strips /* ... */ block comments
• preserves string literals and escaped characters
• UTF-8 safe (operates on chars, not raw bytes)

Usage

use zpl_toolchain_jsonc_strip::strip_jsonc;

let stripped = strip_jsonc(r#"{ "a": 1, /* comment */ "b": 2 }"#);
