macOS: double-click selection doesn't stop on ":" and other characters even if they are in "selection-word-chars"

[akscram]

Issue Description

In 1.3.0 and 1.3.1 when double-clicking on text which contains ":" on a position which is on the left of ":" the selection includes ":". This happens with the default settings and continues happening even if selection-word-chars is explicitly set to its default value which is \t'"│`|:;,()[]{}<>$.

For example, when you have an output of git grep like the following and you want to select include/zephyr/drivers/display.h and you double-click on the path to select it:

Expected Behavior

Only the include/zephyr/drivers/display.h path is selected, like the following:

Actual Behavior

The path and adjacent line number parts are selected:

And other parts as well if they are no split by a space:

See the following recording for the observed behaviour:

Reproduction Steps

2. Execute git grep or grep commands where there is some output
3. Try clicking on the path part

I acknowledge that:

• I have reviewed the FAQ and confirm that my issue is NOT among them.
• I have searched the Ghostty repository (both open and closed Discussions and Issues) and confirm this is not a duplicate of an existing issue or discussion.
• I have checked the "Preview" tab on all text fields to ensure that everything looks right, and have wrapped all configuration and code in code blocks with a group of three backticks (```) on separate lines.
