fix(spelling): Rename identifiers on Typo fixes, add inspection controls, cut false positives (#51)

Root causes: Typo "Change to" replaced one occurrence even for declared names (breaking references); inspections had no Disable / Edit settings controls anywhere; en_US Hunspell does not derive agent nouns like "checkpointer" and compound identifier words were flagged; local inspections (Typo, file references, SQL) never reached Problems.
Fix (IDEA): "Typo: Rename to…" renames via LSP rename, falling back to syntax-based local rename, never a silent single replace, and lists identifier-safe words only; intention submenu (→) with Edit inspection profile setting / Disable inspection for every inspection; Problems and Inspection Results get Disable Inspection, Change Severity, Edit Inspection Profile Setting; Typo options Process code / literals / comments; -er/-ers derivation and identifier compounds accepted, common misspellings still flagged.
Siblings covered: all LSP and built-in inspections' intentions, file reference and SQL inspections in Problems, severity counter.
Verified: ide-spell tests (issue examples + ~50 real misspellings), vitest (286), in-app on macOS: only 'mesage' flagged, submenu, Rename to → 'message' updated both occurrences.
