improvement(landing): rebrand to AI workspace, add auth modal, harden PostHog tracking

[emir-karabeg]

Summary

• Rebrand landing + docs from "workflow tool / automation platform" to "AI workspace" — updates all user-facing copy, SEO metadata, structured data, llms.txt, robots.txt, sitemap.ts, and manifest.ts to reflect the new positioning
• Add inline auth modal (AuthModal) for social login on landing CTAs — users can sign in with GitHub/Google without leaving the page; falls back to /login or /signup when social providers aren't available
• Add /api/auth/providers route to power the auth modal's provider detection
• Harden PostHog event tracking — replace fragile usePostHog() + useEffect([posthog]) pattern with captureClientEvent (fires exactly once on mount); tighten landing_cta_clicked.destination from bare string to an autocomplete-friendly union type; add auth_modal_opened event; add CTA tracking to templates and integration pages
• Add constitution rules (.claude/rules/constitution.md, .cursor/rules/constitution.mdc) codifying language and positioning guidelines for AI-assisted copy editing

Type of Change

• Bug fix
• New feature
• Breaking change
• Documentation
• Other: SEO / branding / analytics

Testing

• Tested locally — landing page, auth modal, social login flow, PostHog events in dev tools
• TypeScript compiles clean (tsc --noEmit)

Checklist

• Code follows project style guidelines
• Self-reviewed my changes
• Tests added/updated and passing
• No new warnings introduced

PR Summary

Medium Risk
Medium risk because it changes authentication entry points on the landing/integrations pages (new modal + provider-detection API) and adjusts analytics event typing/tracking, which can affect conversion flow and instrumentation but not core auth enforcement.

Overview
Updates Sim’s public positioning from “workflow/agentic workforce platform” to “open-source AI workspace” across landing, integrations/models/partners pages, docs content, SEO metadata, structured data/JSON-LD, manifests, llms.txt outputs, and other crawler-facing files (plus adds copywriting “constitution” rules for AI-assisted edits).

Introduces an AuthModal used by major landing CTAs to enable in-place GitHub/Google sign-in (with SSO/email fallbacks and registration-disabled handling) backed by a new GET /api/auth/providers endpoint.

Hardens and expands PostHog tracking by switching page-view events to captureClientEvent (one-time mount), adding auth_modal_opened and login_page_viewed, tightening landing_cta_clicked typings, and adding CTA tracking to templates, landing preview, and integrations pages.

Greptile Summary

This PR rebrands all user-facing copy across the landing pages and docs from "workflow tool / automation platform" to "AI workspace", adds an inline AuthModal component for social (GitHub/Google) and SSO login on landing CTAs, introduces a /api/auth/providers endpoint to power provider detection, and hardens PostHog tracking with a type-safe event catalog and a fire-once captureClientEvent helper.

• The auth_modal_opened event fires in handleOpenChange before providerStatus is guaranteed to have resolved. When the modal is opened while providerStatus === null (fetch in flight) and the server later returns registrationDisabled: true, the event is already recorded with view: 'signup' even though the useEffect subsequently forces view to 'login', making the tracked view inaccurate for that edge case.

Confidence Score: 5/5

Safe to merge — no functional regressions; both remaining findings are analytics edge-case P2s that do not affect the auth flow itself

The auth modal handles the previously-flagged race condition and isProduction leak correctly. All CTA tracking, provider detection, and redirect logic is sound. The two P2 comments concern analytics accuracy in narrow edge cases (modal opened before fetch resolves + registrationDisabled, and destination label when no social providers are configured) — neither blocks correct user authentication.

apps/sim/app/(landing)/components/auth-modal/auth-modal.tsx — minor analytics timing issues around auth_modal_opened event and hasModalContent logic

Important Files Changed

Filename	Overview
apps/sim/app/(landing)/components/auth-modal/auth-modal.tsx	New inline auth modal for social/SSO login on landing CTAs; module-level fetchPromise cache works correctly, but hasModalContent excludes emailEnabled and auth_modal_opened fires before providerStatus settles, causing minor analytics inaccuracies
apps/sim/app/api/auth/providers/route.ts	New public endpoint returning GitHub/Google availability and registrationDisabled flag; isProduction leak from previous review is fixed, response shape is minimal and appropriate
apps/sim/lib/posthog/events.ts	Adds auth_modal_opened event and tightens landing_cta_clicked.destination to an autocomplete-friendly union; all new source values align with component usage
apps/sim/app/(landing)/landing-analytics.tsx	Simplifies landing analytics to fire-once pattern via captureClientEvent; cleaner than previous usePostHog/useEffect pattern
apps/sim/app/(landing)/components/hero/hero.tsx	Hero CTA wired to AuthModal with correct source/destination tracking; copy updated to "AI workspace" branding
apps/sim/app/(landing)/components/navbar/navbar.tsx	Desktop and mobile nav CTAs both use AuthModal with correct sources ('navbar', 'mobile_navbar'); tracking and redirect logic look correct
apps/sim/app/(landing)/components/collaboration/collaboration.tsx	AuthModal added for collaboration CTA with correct source; copy updated to AI workspace branding; existing dangerouslySetInnerHTML for CSS keyframes is pre-existing pattern
apps/sim/app/(landing)/components/pricing/pricing.tsx	All pricing tiers now use AuthModal; tier data still carries unused href fields for community/pro/max that are silently ignored by the render logic (minor dead data)
