[FEATURE] toggle localized /effort

Problem Statement

I often have multiple Claude Code sessions open simultaneously, often with different effort level preferences between them.

However, using /effort to change one of those sessions to the appropriate effort level, for some reason, changes those settings _globally_, making it unusable for changing only the local session.

When I am calling /effort I always only want to change the local session.

Proposed Solution

I'd like to be able to toggle on a setting, and then when the setting is toggled on, /effort only affects the current directory, and if the current directory doesn't have a default explicitly set, then maybe it can affect the current directory's default

Alternative Solutions

Workaround: open all sessions with --effort parameter, never use /effort.

Issue with workaround: finnicky, makes /effort a landmine, no convenient way to change /effort mid-session (I use /exit -> claude -c --effort <effort>)

Priority

Low - Nice to have
