EPIC-08: template upgrades + Ink migration recipes

[RtlZeroMemory]

Summary

• add docs/migration/ink-to-rezi.md with conceptual mapping and practical migration recipes (no Ink compatibility promise)
• link migration guide from FAQ, docs home, and MkDocs nav
• upgrade create-rezi templates (dashboard, file-browser, streaming-viewer, form-app) to showcase polished, production-style UX and Rezi differentiators
• improve create-rezi CLI template discovery (--list-templates highlights, clearer selection/messaging, canonical template naming)
• add deterministic template smoke checks (npm run check:create-rezi-templates) and wire into root check

Template Highlights

• dashboard: live-updating ui.table with stable keys, sort/filter/pin controls, incident telemetry
• file-browser: async command palette with cancellation and request telemetry
• streaming-viewer: ui.virtualList over 15k streams with fast navigation and live ingest feed
• form-app: validation-centric multi-step form, keybinding modes/chords, overlays and toasts

Validation

• npm run lint
• npm run typecheck
• npm run build
• npm test
• npm run test:e2e
• npm run test:e2e:reduced
• npm run test:native:smoke
• npm run docs:build
• npm run check:create-rezi-templates
• scaffold validation per template: npm install --ignore-scripts, npm run build, npm run typecheck, and start script presence

Make check runnable without a prior build

Adding check:create-rezi-templates to the top-level check command makes npm run check fail on a fresh checkout, because that script hard-fails unless packages/create-rezi/dist/scaffold.js and packages/{core,node}/dist/index.d.ts already exist (see scripts/check-create-rezi-templates.mjs guards around lines 73-95). In the common local/CI flow where contributors run checks right after install, check now exits before running any real validations unless they manually run a full build first.
