This is a maintainer-authored, good-first issue in a major proof assistant. Current master still parses all four unary constructors directly and contains no corresponding warning, so the task is live, locally bounded to the rewrite-strategy parser/AST and tests, and externally reviewable.

Warn on nonsensical nested Rocq rewrite strategies
Teach Rocq's `rewrite_strat` front end to emit a named warning for semantically pointless unary-strategy combinations such as `innermost outermost s` and `bottomup topdown s`, while continuing to parse them, and add focused warning-output tests.
Build Rocq, exercise each contradictory unary-strategy pair plus sensible controls, assert the named warning appears only for the intended combinations, and pass the relevant Ltac and output test suites without changing rewrite semantics.
