feat: script mode

Parse and run .sh scripts.

Proof of Concept:

This is a quick and dirty Implementation of .sh file mode, when commands are sequential and do not rely on pipes.

1. Write a script (ex: script.sh) in a text editor and set executable permissions:

nvim script.sh
chmod +x script.sh

2. Identify the lines you want to combine. For example:

#!/path/to/psh
echo "hi this is some text on line 1"
echo "line 2"
ls

4. Combine commands using semicolons: ;

echo "hi this is some text on line 1"; echo "line 2"; ls

This executes all commands sequentially in a single line.

5. Run the script:

./script.sh
# or 
psh ./script.sh

Ensure

• The psh binary is invoked correctly if using #!/path/to/psh
• Or execute the script directly with psh ./script.sh
• Each line in script.sh is transformed into a buffer with terminating ;
• Input this buffer into stdin, simulating manual keyboard input
