[FEATURE REQUEST] recursive project config

Problem

If Claude code is launched from a session that is not at the exact same path as where it was inited before, it does not keep any of the established config. For example when working with git worktrees, if claude code was inited in project/, then a terminal is launched in projcet/branch-1/ and claude is ran, it will not keep the config established in project/.

Desired solution

Configs should be picked up recursively and merged. So a config created for project/ should apply when launching claude in project/branch-1/, as well as any config that is set specifically for project/branch-1/.
