Plan mode ignores user instruction to keep plans inside project directory

Bug

When plan mode is active, the system message directs Claude to write the plan file to a global path:

~/.claude/plans/<generated-name>.md

This conflicts with user instructions (stored in memory/CLAUDE.md) that specify plans must stay inside the project directory. Claude follows the system message path instead of the user's instruction.

Expected behavior

The plan mode default path should respect user-configured preferences, or at minimum, Claude should prioritize user instructions over the default plan path.

Steps to reproduce

1. Save a feedback memory or add to CLAUDE.md: "Plans must stay inside project directory"
2. Enter plan mode
3. Claude writes the plan to ~/.claude/plans/ despite the user instruction
