…ntries, element_at) Closes apache#1448 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

element_at is already a Python-only alias for map_extract, so the Rust binding is unnecessary. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
make_map now takes a dict for the common case and also supports separate keys/values lists for column expressions. Non-Expr keys and values are automatically converted to literals. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
map() now supports three calling conventions matching upstream:
- map({"a": 1, "b": 2}) — from a Python dictionary
- map([keys], [values]) — two lists that get zipped
- map(k1, v1, k2, v2, ...) — variadic key-value pairs
Non-Expr keys and values are automatically converted to literals.

- Add examples for all three map() calling conventions - Use clearer descriptions instead of jargon (no "zipped" or "variadic") - Break map_keys/map_values/map_extract/map_entries examples into two steps: create the map column first, then call the function Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
