[FEATURE] Inline in-cell editing for notebooks (Ctrl+I equivalent) in the VSCode extension

Problem Statement

Problem: In Jupyter notebooks, Copilot's Ctrl+I opens an inline prompt inside the cell — type an instruction, it edits that cell in place. Claude Code can edit cells (via NotebookEdit) but only through the side panel, which is heavier for quick single-cell tweaks.

Proposed Solution

Request: A keybinding in the VSCode extension that opens an inline prompt anchored to the current notebook cell (or selection), edits it in place as an accept/reject diff, and uses neighboring cells + Jupyter kernel variables as context.

Alternatives: Select + ask in the panel (works, but heavier); Copilot's Ctrl+I (not Claude); Cline's per-cell buttons bound to a shortcut (different extension).

This closes a real gap for notebook-heavy / data-science workflows where iteration is cell-by-cell.
