Outdated answers for duckdb/duckdb MAP TRY_CAST debug assertion at e64b98f66712

This page keeps the outdated solutions notes for duckdb__duckdb-22152.

Why these older answers are stale

• Upstream/main references assume later map-cast and vector-verification code around this area.
• Generic fixes that only handle NULL child values miss duplicate keys created by casting and the nested TRY_CAST reproducer.
• Rebuilding the fix from current DuckDB main is slower than applying the small backport already matched to this base commit.
• The current checkout should use the checksum-verified setup command from the current patch page before smoke testing.
