perf: replace 'in dict.keys()' with 'in dict' for better performance

[christopherrya]

Remove unnecessary .keys() calls in dictionary membership checks. This avoids creating view objects and improves readability.

• core/dbt/context/base.py: diff_of_two_dicts()
• core/dbt/contracts/graph/manifest.py: build_node_edges(), build_macro_edges()
• core/dbt/task/init.py: profile check
