leftibot 092ec417d2 Fix #628: Grammar railroad diagram (#673) ... * Fix #628: Add EBNF grammar for railroad diagram generation Add a formal EBNF grammar file (grammar/chaiscript.ebnf) that can be pasted into rr (https://www.bottlecaps.de/rr/ui) to produce navigable railroad diagrams of ChaiScript's syntax. The grammar was validated against the parser implementation and covers all language constructs including class inheritance, guard conditions, raw strings, and const declarations that were missing from the original proposal. A reference section was added to the cheatsheet, and a regression test exercises every documented grammar construct. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * Address review: add grammar railroad diagram link to README Add a Grammar section to readme.md linking to the EBNF grammar file and to mingodad's railroad diagram generator for direct viewing. Requested by @lefticus in PR #673 review.
