v0.8.4 - Early mutation typo fix

[0.8.4] - 2026-05-21

Fixed

• Optimised shell history matching pool logic within functions/history to resolve early mutation typos (e.g., ccd instead of cd). Implemented a deterministic single-character prefix filter that preserves argument matching inside trailing directories while preventing wide-pool history pollution from unrelated commands.

Known Issue

• Mend will not be able to match a typo and suggest fix if it happens at the very first character. This is a sacrifice that has been well thought through during testing to limit unrelated outputs in the fuzzy-search.
