[FEATURE] Better plan usuability

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

The problem:

• Plan files get random unreadable names (compiled-conjuring-corbato.md)
• No project-scoping (all plans dumped in one global ~/.claude/plans/)
• No index or manifest linking plan files to projects
• After closing a terminal, there's no way to know which plan file belongs to which project without opening each one
• Claude Code itself can't help you find "the plan for project X" without already knowing the filename

Proposed Solution

When you are into plan mode you can ask CLAUDE to save current plan with a clear name that will be stored into local .claude folder with maybe a flag "onwork" "done" something like plan-[user name of plan]-[planned|implemented].md thus when you restart CLAUDE you can ask let's focus again on plan X.
