Shell Completion Support

What: Added intelligent tab-completion for bash and zsh shells when typing commands in the Bash tool How to use: While typing a command in the Bash tool, press Tab to see completion suggestions for:

• Commands (e.g., git st → git status)
• Files and directories (with trailing / for directories)
• Shell variables (for inputs starting with $)

Details:

• Automatically detects your shell type (bash or zsh) from $SHELL environment variable
• Context-aware completion: determines whether you're typing a command, file path, or variable based on cursor position
• Bash completion uses compgen -c (commands), compgen -f (files), compgen -v (variables)
• Zsh completion uses native zsh parameter and command arrays
• Limited to 100 suggestions per request for performance
