Add spec_generator workflow with API research step, improve component_generator

- New spec_generator workflow: plain English description → rich JSON spec with
  props, dependencies, and API integration details
- API research step detects external APIs and documents exact endpoints, auth
  methods, response shapes, and implementation notes
- Component generator now receives API integration context and passes it to the
  React component prompt, producing correct fetch code with null safety
- Fix evaluator: switch from generateObject to generateText + manual JSON parse
  to avoid nested Zod schema failures
- Fix propsGrouped check: replace regex with brace-depth counting parser to
  handle curly braces in string values (e.g. "{count} open positions")
- Add vite-env.d.ts to scaffold template for CSS import TypeScript support
- Add Greenhouse job board test scenario for API integration testing

+When the component needs to fetch data from an external API:
+- Use `useEffect` + `useState` for data fetching (loading → data | error states)

+- Show a loading state (spinner or "Loading..." text) while fetching
+- Show an error message if the fetch fails
+- Accept API keys/tokens as props so Webflow designers can configure them in the panel

 ## Role
-You create simplified Webflow component declarations. Given a full declaration with many props, you produce a "client-friendly" version that only exposes the props a non-technical user would need to configure.
+You create simplified Webflow component declarations for client handoff. Given a full declaration with many props, you produce a drastically reduced version with only the props a non-technical client would realistically need to change.
 
 ## Context
-Agencies building Webflow code components often create two versions:
-1. **Full version**: All props exposed — layout variants, animation settings, spacing, every text field. For developers building the site.
-2. **Simple version**: Only the core content props — text, links, images, key toggles. For clients editing content after handoff.
-
-Both versions use the SAME React component and CSS. The only difference is which props appear in the Webflow Designer panel.
-
-## What to KEEP in the Simple Version
-- **Text and TextNode props**: All user-visible text content (headings, descriptions, button text, labels)
-- **Link props**: All URLs/links (CTAs, navigation)
-- **Image props**: All images
-- **Visibility props**: Show/hide toggles for major sections
-- **Key Boolean props**: Important on/off switches that affect content (e.g., `showFooter`)
-- **Id prop**: Always include for CSS/JS targeting
-
-## What to REMOVE in the Simple Version
-- **Variant props**: Layout options, size variants, style variants
-- **Number props**: Spacing, sizing, animation duration, counts
-- **Style/config Booleans**: Technical toggles (e.g., `fixedWeeks`, `showWeekNumbers`)
-- **Behavior props**: Animation settings, interaction config
+Agencies building Webflow code components create two versions:
+1. **Full version**: All props exposed — every text field, layout variant, animation setting. For the developer/agency building the site.
+2. **Simple version**: ONLY the props a client would change when editing their own site. This is the handoff version.
+
+Both use the SAME React component and CSS. The React component has sensible defaults for all props, so anything not exposed in the simple version just uses its default.
+
+## The Client Handoff Test
+
+Ask yourself: **"After the agency hands off the site, what would the client realistically change?"**
+
+A client editing their pricing page would change:
+- Plan names and prices (they updated their pricing)
+- CTA button text and links (they changed their signup flow)
+- Whether a section is visible (they dropped a tier)
+- The main heading (they rebranded)
+
+A client would NOT change:
+- Billing period format ("/month" → they'd just ask the agency)
+- Feature list details (too granular, they'd ask the agency)
+- Descriptions/subtitles (set once during build, rarely touched)
+- Layout direction (horizontal vs vertical — that's a design decision)
+- Badge text ("Most Popular" — set during build)
+- Footer copy (set once, rarely changed)
+
+## What to KEEP (target: 8-15 props)
+
+**Always keep:**
+- `id` (Id) — always include
+- Primary headings/titles (TextNode) — the main text a client sees
+- Primary values that change often (Text) — prices, names of things
+- CTA/action text (Text) — button labels
+- CTA/action links (Link) — where buttons go
+- Section visibility (Visibility) — show/hide major sections
+
+**Keep only if the component has them:**
+- Image props — hero images, logos
+- Key toggles — prominent on/off switches the client controls
+
+## What to REMOVE
+
+- **ALL Variant props** — layout, size, style, theme (design decisions, not content)
+- **ALL Number props** — spacing, counts, durations (technical config)
+- **Secondary/supporting text** — descriptions, subtitles, feature lists, period text, badge text, footer copy
+- **Technical Booleans** — config toggles the client wouldn't understand
+- **Behavior props** — animation settings, interaction config
+
+## Prop Reduction Examples
+
+**Pricing Table (32 props → ~14 props):**
+Keep: id, heading, tier1Name, tier1Price, tier1CtaText, tier1CtaLink, tier1Visible, tier2Name, tier2Price, tier2CtaText, tier2CtaLink, tier2Visible, tier3Name, tier3Price, tier3CtaText, tier3CtaLink, tier3Visible
+Remove: layout, subheading, tier*Period, tier*Description, tier*Features, tier2Recommended, badgeText, footerText, showFooter
+
+**Calendar (8 props → 3 props):**
+Keep: id, header, footer
+Remove: size, captionLayout, showOutsideDays, showWeekNumbers, fixedWeeks
+
+**Hero Section (20 props → ~8 props):**
+Keep: id, heading, ctaText, ctaLink, heroImage, backgroundImage, showCta
+Remove: layout, headingSize, subheading, overlayOpacity, animationDuration, parallaxEnabled
 
 ## Rules
-1. Import the SAME React component from the same path
-2. Import the SAME CSS file
-3. Change the `name` field to `"{{ componentName }} (Simple)"` so both show in the library
-4. Keep the same `description`, `group`, `ssr`, and `applyTagSelectors` values
-5. Only include the subset of props described above
-6. Keep all prop configurations (name, group, tooltip, defaultValue) identical to the full version

+2. Set `name` to `"{{ componentName }} (Simple)"` so both show in the Webflow library
+3. Keep the same `description`, `group`, `ssr`, and `applyTagSelectors` values
