Charis 52a25c2ebb refactor(sql-editor): extract AI/diff + shortcuts hooks (decompose 5/6) (#47935)
## What

Decompose step **5 of 6** for `SQLEditor.tsx`. Extracts the Assistant /
diff cluster and the keyboard-shortcut wiring out of the
`SQLEditorContent` monolith into two focused, individually-testable
hooks:

- **`useSqlEditorAi`** — SQL completion (`complete`), the ask-AI prompt
flow (`handlePrompt`), accept/discard diff handlers, `onDebug` /
`buildDebugPrompt` helpers, `handleDiffEditorMount`, and the fragile
diff lifecycle effects (one-shot diff-request drain, diff-editor value
sync, ask-AI widget visibility).
- **`useSqlEditorShortcuts`** — the registered shortcuts (focus editor,
new snippet, format, explain) plus the accept/discard/escape keydown
handling.

`SQLEditorContent` now composes these hooks alongside the
execution/explain hooks landed in decompose 4.

## Behavior-preserving

This is a pure extraction. The moved function bodies, effect logic,
dependency arrays, and JSX are unchanged from the previous monolith
(verified via `git diff` against the pre-decomposition source). In
particular:

- `useEffectEvent` is preserved for `drainDiffRequest` / `resetDiff`.
- `editorMountCount` remains single-owner (passed into the AI hook to
drive the one-shot drain).
- The untrusted→safe SQL promotion (`acceptUntrustedSql`) continues to
happen in the run/explain gesture and warning-modal handlers in
`SQLEditorContent`, as close to the explicit user action as possible.

The Phase-1 characterization suite (`SQLEditor.test.tsx`, 11 tests)
remains green.

## Stack

Part of the SQLEditor decomposition stack (1/6 … 6/6). Builds on
decompose 4 (execution + explain hooks, #47923). Next: PR6 splits the
JSX into panes + final cleanup.
