## Description

<!-- SECTION:DESCRIPTION:BEGIN -->
Wire Harper's fixes/ignore into the Alt+; popup. Currently glint only renders green grammar underlines (TASK-043). Harper advertises codeActionProvider + executeCommand commands (HarperIgnoreLint, HarperAddToUserDict, HarperAddToFileDict, HarperAddToWSDict). Add: on a grammar span at cursor/click, send textDocument/codeAction for the diagnostic range -> show returned fixes as replacement rows in the proofing popup (reuse spellOption/applySpell plumbing); Ignore -> executeCommand HarperIgnoreLint; Add to dict -> HarperAddToUserDict. Needs: LSP client request/response correlation (id->reply channel; the current client only fires notifications + answers server requests), codeAction result parsing (WorkspaceEdit / Command), and mapping the grammar Diag back to harper's diagnostic (code+range). Store the raw LSP diagnostics (code, range, data) alongside the rune-mapped Diag so codeAction can reference them.
