/**
 * Legacy regex-based Hono convention extractor.
 * Preserved as a kill-switch fallback (CODESIFT_LEGACY_HONO=1) during
 * the migration to the tree-sitter AST extractor.
 *
 * This file is a verbatim copy of the original regex functions from
 * project-tools.ts as of 2026-04-10 (pre-AST migration).
 *
 * DO NOT MODIFY — this is the frozen legacy implementation.
 * Delete after 2-week migration window per spec rollback strategy.
