Fuzzy matcher should favour whole words

[davep]

[Meta: note that changes to the fuzzy matcher are in process in #3058 -- this is mostly a reminder to myself to either make this change there are do this as a close followup once the PR is merged]

The fuzzy matcher should favour finding a complete word over finding the start of the letter collection as early as possible. The issue can be seen here:

poo should match poo in pile_of_poo (and so giving a higher score) in preference to matching the earlier instances of p and o.

@davep this still seems to be happening, but even more weirdly. I'm using it for searching through paths and it is very odd. I'm using fzf to do the searching right now because it is incorrectly eliminating results (but fzf doesn't do highlighting so Matcher is doing the highlighting).

You will see that SimplePropertyLabel, PropertyLabelRetestButton, and RollableLabel aren't highlighted because Matcher incorrectly eliminated those but fzf did not. On PropertyTextInput you see it is picking up text from the right side and as soon as I add 't' to my query it also is incorrectly eliminated.

(thanks for all your work on this awesome TUI framework)

@gunslingerfry Note that this is quite an old issue, and also I've not been involved with Textual for quite some time now. I think I saw mention that the maintainer made some changes to the default matcher; it might be sensible for you to raise an issue if you feel you've found a problem.

My apologies. I will create a new issue. Thanks!

I hope I solved your issue!
