[BUG]: Spell checker stops flagging errors depending on adjacent words

[sagohub]

Issue Description

Hey! First of all, thanks for this extension, it's been really helpful for catching typos in my code. I'm using it in Zed with PHP and I think I found a bug.

It seems like the spell checker inconsistently flags errors depending on what comes after (or around) the misspelled word. Here are two scenarios where I reproduced it:

---

Scenario 1 - Misspelled word inside a string

When the string path ends with an incomplete/invalid word, the error is flagged correctly:

return view('administraton/dashb', $data);

administraton (missing the "i") is correctly underlined. ✔️

But when the path ends with a valid dictionary word, the error disappears:

return view('administraton/dashboard', $data);

administraton is no longer flagged, even though it's still misspelled.

Expected result:

---

Scenario 2 - Misspelled segment in a camelCase function name

When the function name ends with an incomplete/invalid word, the error is flagged:

public function getConseGroupSal() // I left out the 'e' in Sal()

Conse is correctly underlined. ✔️

But when the function ends with a valid word, the error disappears:

public function getConseGroupSale()

Conse is no longer flagged.

Expected result:

---

Expected behavior
A misspelled word/token should be flagged regardless of what comes before or after it. The validity of adjacent tokens shouldn't affect the detection of an already-invalid one.

Hey, thanks for the report! For the first case at least, it's getting caught in the base64 ignore regex. I'm going to relax it to require at least one = at the end. Not ideal, but a perfect b64 regex is hard (or impossible) to do. Although I could not reproduce the getConseGroupSal issue, I suspect it's the same problem. I need to push some other fixes, but the next version should work better :)
