Notebooks 3/4: run cells from the side-pane notebook viewer #212
Description
Part of #208, after 2/4. Design doc: ~/.local/share/t3-fork-notes/notebook-execution-design.md, sections 3 and 7 (PR 3).
A small hook in upstream's NotebookPreview.tsx adds Run, Run all, Interrupt and Restart, live outputs, dirty/save/conflict/reconnect states, and a static fallback when no Jupyter server is available. Sanitize outputs. Use components/ui primitives without restyling them. Focused browser tests; the visual proof is a capture.

Implemented #212 and committed locally. Working tree is clean.
24f77861e84f08a7927d87cf9879e1fcd56b40a9issue-212-notebooks-3-4-run-cells-from-the-side/home/tnnrpolley21/Workspaces/Applications/t3code/.worktrees/issue-212-notebooks-3-4-run-cells-from-the-sideThe workspace notebook hook now provides Run cell, Run all, Interrupt, Restart, and Save through destination-environment T3 RPC. It includes cell-local live outputs, execution counts and provenance, unknown/reconnect states, permission-controlled actions, and static fallback. Rendering reuses the existing output decoder, sanitizer, isolated HTML frames, and incremental cell reveal.
Dirty closing offers Save, retain draft, or discard, including for inactive tabs and disconnected viewers. Discard uses a new protected, revision-checked server reload method under the existing notebook lock; it does not write the disk file.
Entry points covered: workspace file side pane and artifact workspace opens through the same dispatch hook. Desktop inherits web behavior. Attachments remain static; mobile and MCP are outside this change.
Validation:
check:changedremains blocked only by the established baseline: 3 mobile type errors, 3 Knip files, and 74 Knip exports.Evidence: live viewer capture, static sanitized-output capture, final gate log.
No push, PR, merge, dev server, interactive browser session, install/restart, or release was performed. Independent checker review and the primary orchestrator’s separately authorized integrated preview remain open.
