Introduces `parsedRefsCache` in `Workspace` to prevent repeatedly executing the heavy `XREF_SCAN_RE` regex across the same unchanged sheet text during cache invalidations. Co-authored-by: Horizontal42 <75383519+Horizontal42@users.noreply.github.com>

2025-02-18 - Repeated Regex Execution Caching
Learning: In recursive or looping traversal like graph cycle detection (e.g. invalidation of multiple sheets), running heavy Regex (matchAll) repeatedly on the exact same text is extremely slow and compounds exponentially.
Action: Introduce text-based short-circuiting caches (e.g., matching the original text property against the cached payload string) where text extraction logic like Regex or parsing runs purely on deterministic inputs.
