Fix false positive for 'co-founded' in PronounVerbAgreement linter

[nmurrell07]

Summary

Fixes incorrect dictionary tag for "co" by removing an erroneous I marker from its part-of-speech annotation.

The Bug

The word co was incorrectly tagged with an I flag in the dictionary definition:

- co/~NSI(dE
+ co/~NS(dE

This extra tag likely causes incorrect grammatical analysis or spell-check behavior for this word (e.g., treating it as a different part of speech than intended).

What This Change Does

Removes the I character from the dictionary entry's tag string. The remaining tags (~NS(dE) appear to be the correct annotation for "co" in Harper's linguistic format.

Note: Without access to the original issue thread (API returned 404), I cannot confirm exactly what semantic meaning the I flag represents or which specific bug this resolves. Based on common dictionary tag conventions, it may indicate an incorrect part-of-speech classification.

Verification

To verify this fix:

1. Test spell-check behavior for sentences containing "co" to ensure no false positives/negatives
2. Check grammar analysis if Harper provides grammatical parsing - confirm "co" is now classified correctly
3. Run existing test suite to ensure no regressions in dictionary-related tests

# Example verification command (adjust based on project structure)
cargo test --package harper-core

Limitations

• Original issue context unavailable (404 errors from GitHub API)
• Cannot confirm the exact semantic meaning of the removed I flag without documentation or maintainer input
• No specific failing test case identified to demonstrate before/after behavior

If this change doesn't resolve the intended bug, please share more details about what behavior was expected vs. observed.

The meanings of the dictionary annotation flags are in annotations.json. The # field of each entry is a brief description, and the optional // field can contain an additional comment of any kind.

co/~NSI(dE

• co - the word
• / - delimits the word from the annotation flags
• ~ - denotes that a word is common
• N - denotes that the word is used as a noun (not necessarily exclusively)
• S - tells Harper to generate another word from this word by adding -s or -es following certain orthographic rules. Normally to generate a plural in the case of a noun and a third-person singular present form of a verb. But as the dictionary originated as one from a spellchecker where the only job of the annotation flags was to enable affix compression, there are quote a few uses where they just lead to the creation of extra words that coincidentally end is -s or -es but are not necessarily related to the main word itself. This is probably a factor in this issue.
• I - denotes that can word has at least one pronoun sense. Formerly the 8 flag was used for this as mentioned in the previous version of the comment. Either way co is only a pronoun in the most marginal way and this should be removed.
• ( - denotes that the word can be used as a prefix as well as a word in its own right. (Prefixes that don't also occur as words don't belong in dictionary.dict at this time.)
• d - tells Harper to generate another word from this entry by adding -ed. Normally to generate the past tense and past participle of regular verbs. But as with -S above it is historically used to derive words unrelated to the main word. Here it results in the word coed, which should have its own independent entry.
• E - I have to look this one up ... This is also a leftover from the affix compression heritage of the file. It generates a dew word by adding the dis- prefix. Here it generates disco, which should also have its own independent entry.
