Retargeted to main (main-first flow, #11696). Dependabot security updates always open against the default branch; this workflow re-applies the retarget after every Dependabot push, so rebases cannot revert it.

Routine dependabot patch bump (1.9.0→1.9.1): floor-only, single line, scoped to autobot-backend/code_analysis/requirements.txt. Release notes: bug fixes only, first version supporting Python 3.15, no breaking changes. No other requirements files touch this dependency's version pin. CI: no failing checks (mergeStateStatus was flagged blocked by mergeable-conflict state only, not CI — see thread).
