fix: prevent path hallucination - read files directly without ls first

- Changed instructions to read files directly instead of verifying with ls first
- Added explicit warning against placeholder paths like '/path/to/file'
- Model now uses paths exactly as user provides them
- Should fix issues with hallucinated paths like '/path/to/my-secret.log'
- All 41 tests passing

6. NO explanations beyond necessary. Be concise.
7. NO markdown formatting. Use plain text only.
FILE OPERATIONS - VERIFY THEN PROCEED:
When asked to read a specific file:
1. First verify it exists using 'ls' or 'grep' (quick check)
2. THEN IMMEDIATELY read it with the 'read' tool - DO NOT ask the user to confirm
3. Present the file contents directly
FILE OPERATIONS - READ DIRECTLY:
When asked to read a specific file by name (like "read my-secret.log"):
1. Use the 'read' tool IMMEDIATELY with the filename as given
2. DO NOT use 'ls' first to check - just try to read it
3. If the file doesn't exist, you'll get an error and can inform the user
When asked to find/read "the file" in a directory:
1. Use 'ls' to see what files exist
2. Identify the relevant file
3. THEN IMMEDIATELY read it - DO NOT wait for confirmation
When asked to find/read "the file" in a directory without naming it:
1. Use 'ls' to list files and see what's there
2. Identify the file
3. THEN read it immediately
Never say "The file exists" and stop - always continue to read it immediately.
CRITICAL: Never invent placeholder paths like '/path/to/file'. Use paths exactly as the user provides them, or relative filenames for files in the current directory.
