Changelog

v2.1

Made the installer compatible with minimal Calculinux environments by replacing install -m with cp followed by chmod.

Bash shell integration is installed automatically through ~/.bashrc.
Multi-command actions execute as one TUI handoff; TUI is not redrawn between commands.
Each generated command is added to Bash history.
Failed commands stop the current action and pause on a read before TUI resumes.
Marks are stored as absolute paths and survive directory changes.
Returning to a directory shows its previously marked entries again.
Moving marked entries uses the current TUI directory as the destination.
.tui lookup is limited to the user's home directory.

Hidden files and directories are hidden by default; use tui -a / tui --all to show them.
Added a synthetic parent-directory entry at the top of every listing.
Left arrow moves the cursor to the parent entry; pressing left again moves to the parent directory.
Navigation is limited to the directory containing the applicable .tui file.
Added ls --color-style colors for directories, symlinks, executables, archives and common image files.
Marked paths remain visible as marked when returning to their directory.

Added tui -v / tui --version for verifying which installed version is running.
Fixed Ctrl+C exit so the parent Bash process changes to the directory where TUI was closed.
TUI now uses a separate exit status for normal Ctrl+C exit versus shell-action handoff.
Shell actions are read into an array before execution, so commands containing read, &&, and || receive the real terminal stdin and behave like normal Bash commands.
