deep_nesting

Blocks nested deeper than [flux] max_nesting.

Each if, loop, match, and function inside another adds a level the reader has to hold. Return early, invert the condition, or move the inner block into its own function. The limit is max_nesting in [flux], five by default.

Set its level in the [lint] table of alloy.toml, or for one file with --@alloy-lint.
