Inconsistent CLAUDE.md Loading and Instruction Handling

Bug Description
Title: CLAUDE.md not loaded with @ symbol and ignored when loaded

Description:
Two related issues with CLAUDE.md handling:

1. Inconsistent loading: When referencing files with @ symbol (e.g., @src/components/ui/sidebar.tsx), CLAUDE.md is not loaded. When using natural language (e.g., "Please explain sidebar.tsx"), CLAUDE.md is loaded as shown in the output.

1. Instructions ignored: Even when CLAUDE.md is successfully loaded, Claude Code does not follow the instructions within it. Tested with simple imperative instructions like "start every response with a joke" - the instruction was completely ignored despite the file being read.

Expected behavior:

• CLAUDE.md should load consistently regardless of reference method
• Instructions in CLAUDE.md should be followed when loaded

Actual behavior:

• With @: Only the referenced file is read
• Without @: Both file and CLAUDE.md are read, but instructions ignored

This affects context awareness and makes CLAUDE.md unreliable for project-specific guidelines.
