Shell snapshot generation drops first character of shopt output

Description

When Claude Code generates shell snapshots in ~/.claude/shell-snapshots/, the first shopt line has its leading s character dropped, resulting in hopt instead of shopt.

Steps to Reproduce

1. Start a Claude Code session on Windows with Git Bash
2. Let Claude Code generate a shell snapshot
3. Observe the snapshot file contents

Expected Behavior

Line 25 should read:

shopt -u localvar_unset

Actual Behavior

Line 25 reads:

hopt -u localvar_unset

This causes the error:

/c/Users/rob/.claude/shell-snapshots/snapshot-bash-XXXXX.sh: line 25: hopt: command not found

Environment

• OS: Windows 11 (MINGW64_NT-10.0-26200)
• Shell: Git Bash (MSYS2)
• Claude Code Bash tool uses /usr/bin/bash

Evidence

The bug is reproducible - deleting the snapshot and letting Claude Code regenerate it produces the same error. The issue appears to be in the snapshot generation logic, not a one-time corruption.

Example from generated snapshot:

alias -- ~='cd ~'
hopt -u localvar_unset    # <-- missing 's' at start
shopt -s login_shell      # <-- subsequent lines are correct
shopt -u mailwarn

Workaround

Manually fix the file:

sed -i 's/^hopt /shopt /' ~/.claude/shell-snapshots/snapshot-bash-*.sh

This fix is lost when Claude Code regenerates the snapshot.
