/resume shows empty list for projects with spaces in path

Problem

The /resume command shows an empty list for a project whose path contains spaces, even though:

1. Sessions exist and are properly indexed
2. --continue flag works correctly (continues most recent session)
3. Global session view (Ctrl+A) shows all sessions including those from this project
4. The sessions-index.json is valid JSON with correct structure

Environment

• Claude Code version: 2.1.15
• Platform: macOS (Darwin 25.2.0)

Reproduction

1. Have a project at a path with spaces, e.g., /Users/mll/Main/10 Projects/05 Utils/HumbleB
2. Create some sessions in that project
3. Run claude (or wrapper that calls claude)
4. Type /resume
5. Expected: See list of sessions for this project
6. Actual: Empty list shown

Investigation

• Project directory exists at ~/.claude/projects/-Users-mll-Main-10-Projects-05-Utils-HumbleB/
• sessions-index.json contains 33 valid entries
• All entries have correct projectPath matching the working directory
• originalPath field matches the working directory
• File permissions are correct (0600)
• No symlinks in the path
• Running pwd and pwd -P show identical paths

Workaround

Using --continue flag works to continue the most recent session.

Hypothesis

The /resume command may have a bug in path matching/filtering when the path contains spaces, even though the space-to-dash encoding in the directory name is correct.
