[BUG] Invalid alias generation with double dashes: `alias -- -- -='cd -'`

Environment:

• Platform: Anthropic API
• Claude CLI version: 1.0.81 (Claude Code)
• Operating System: macOS 15.6 (24G84)
• Terminal: iTerm2 and VSCode Terminal
• Shell: bash

Bug Description:
Claude Code generates invalid bash aliases in shell snapshots with syntax:
alias -- -- -='cd -'

This causes the error:
alias: --: not found

Expected behavior:
Should generate valid alias syntax like:
alias -='cd -'

Location:
~/.claude/shell-snapshots/snapshot-bash-*.sh around line 181

Impact:
Non-critical but generates error messages during script execution.
