Epic: workflow canvas node selection, manual-edit wiring, and Pilot mode

[graycyrus]

Summary

Three related gaps in the Workflows console surface:

1. Node selection is entirely missing on the visual canvas — frontend/src/views/workflows/graph.ts has zero click/select interaction today.
2. Manual editing already exists (WorkflowCreateDialog.tsx is a full CRUD editor) but isn't wired to the canvas — you can't click a node and edit it inline.
3. "Pilot" mode doesn't exist — no code anywhere lets an operator drive/step a live run from the canvas, only passively view it.

Also folds in #1923 (globals aren't editable in general — this epic scopes the workflow slice of that broader ask).

Plan

• Click-to-select nodes on the visual canvas
• Wire WorkflowCreateDialog inline editing to the selected canvas node
• globals: nothing is built in — a company must be able to edit, rename, remove and re-add every baseline task, workflow, ledger, teammate and skill #1923 — scope the workflow slice of globals editability (flag the broader ledgers/teammates/skills ask separately)
• Pilot mode: drive/step a live run from the canvas, not just view it

Part of

September 2026 roadmap.
