[BUG] `claude --resume` session picker hangs indefinitely (tmux + Alacritty)

Description

Running claude --resume without a session ID hangs indefinitely. The interactive session picker never appears - the CLI just hangs with no output until Ctrl+C.

Environment

• Claude Code version: 2.1.27
• OS: macOS 14.6.1 (Build 23G93)
• Terminal: Alacritty 0.16.1 + tmux 3.5a
• TERM: tmux-256color
• COLORTERM: truecolor

Steps to Reproduce

1. Open Alacritty with tmux
2. cd to a project directory with existing sessions
3. Run claude --resume
4. Observe: CLI hangs with no output, session picker never renders

Expected Behavior

Interactive session picker should appear allowing selection of a session to resume.

Actual Behavior

CLI hangs indefinitely with no output. Must Ctrl+C to exit.

Workarounds That Work

The following alternatives work correctly:

• claude --continue - resumes most recent session without picker ✅
• claude --resume <session-id> - resumes specific session without picker ✅

This suggests the issue is specifically with the interactive session picker TUI component, not with session loading or resume functionality itself.

Debug Information

Sessions index size: 4.2K
Number of sessions: 6

Session files are small (not the large tool output issue from #21067):

Possibly Related Issues

• #17787 - TUI input broken on macOS (DSR 6 cursor position responses leak)
• #15694 - --fork-session flag ignored with TUI session picker
• #19090 - Session resume freezes when searching by GUID

Note: tmux is the recommended workaround for #17787, yet the session picker still hangs inside tmux.
