Output command fails to parse absolute file paths

[tmchow]

Bug

The Output command cannot parse absolute paths. For example:

Output /tmp/demo.gif

Fails with:

  2 │ Output /tmp/demo.gif
      ^^^^^^ Expected file path after output

  2 │ Output /tmp/demo.gif
             ^^^ Invalid command: tmp

  2 │ Output /tmp/demo.gif
                  ^^^^^^^^ Invalid command: demo.gif

Relative paths work fine: Output demo.gif.

Reproduction

vhs new test.tape
vhs test.tape

The generated template includes Output /tmp/test.gif which fails immediately.

Root Cause

The lexer treats / as a regex delimiter (case '/' in lexer.go), so /tmp/demo.gif tokenizes as REGEX("tmp") + STRING("demo.gif") instead of a single path token. The parser's parseOutput() only accepts STRING tokens after Output.

Workaround

Quote the path: Output "/tmp/demo.gif"

Environment

vhs version v0.11.0 (c6af91a)
macOS 15.5

Implemented in #742 - adds a parsePathArgument helper that reconstructs absolute paths from the REGEX + STRING token sequence the lexer produces for /paths/like/this.gif.
