Rewrite the README around the new Hexclave name with a revised intro,
an AI-agent setup flow, the apps catalog, an SDK table, and a
contributing section. Fix a stale anchor in CONTRIBUTING.md that
pointed to a README section removed in the rewrite.

Embed the Hexclave header SVG at the top of the README. Replace the
"What's included" table with a per-app pattern: logo, app name,
description, and dashboard screenshot. Remove the SDKs section.

New assets in .github/assets/: hexclave-header.svg, 10 app logos
cropped from the dashboard apps catalog, and dashboard screenshots
for Analytics and Launch Checklist. The existing storeDesc-*.png
files in apps/dashboard/public/ are reused for the other 8 apps.

Remove the doctoc-generated TOC at the top of the README since it
sat above the centered header and contained stale entries. Embed
the Jersey 10 web font directly into hexclave-header.svg as a
base64 data-URI so the wordmark matches the landing page when
rendered standalone.

In "What's included", drop the per-app dashboard screenshots and
extend each app's one-liner into 1-2 sentences pitching its
specific features. Copy adapted from the per-app pages on the
hexclave landing site. Delete the now-unused screenshot files
from .github/assets/screenshots/.

- Replace "and many more features, so you don't have to build it
  yourself" with the tighter "and much more" in the intro paragraph.
- Tighten the hexclave-header.svg viewBox from 200x48 to 162x48 so
  it fits the actual content. The old viewBox left ~22% empty space
  on the right, which made the centered logo appear shifted left
  on GitHub.
- Drop "Python" from the SDKs badge. Hexclave does not ship a
  Python SDK; the JS SDK and REST API cover that use case.

Add README-1.md to test an alternative layout for the 'What's included'
section. Each app is rendered as a 2-column table: heading, logo, and
description on the left; a focused, zoomed-in screenshot on the right.

Authentication uses the Sign-in live preview card from the auth-methods
page; Teams uses a cropped team detail view with members and permissions.
Only Authentication and Teams are populated for now to evaluate the
layout before applying it across all apps.

Screenshots live in .github/assets/app-shots/.

Apply the side-by-side pattern to all 10 apps in 'What's included'.
Every app screenshot is now 1100x500, captured from the local
dashboard in dark mode, and padded with the GitHub dark theme
background color (#0d1117) where needed so they blend into the
README page.

Each app shows its most distinctive feature view:
- Authentication: sign-in methods config + live preview side by side
- Teams: team detail with members and permissions
- RBAC: team permissions list with descriptions
- API Keys: API key settings card with type toggles
- Payments: product lines catalog with a real product card
- Emails: sent log with subjects, statuses, and domain reputation
- Analytics: users table with seeded demo data
- Webhooks: 'Create new endpoint' modal
- Data Vault: 'Create Data Vault Store' modal
- Launch Checklist: progress tracker with 0/6 checks completed

Address feedback that several screenshots looked weirdly cropped or
empty:

- Authentication: wider viewport (1800) so both Sign-In Methods config
  and the Live Preview sign-in card are fully visible, no longer half-
  cropped.
- API Keys: tighter crop to the centered content cards, no longer
  truncated on the right.
- Payments: crop starts below the test-mode banner and stripe-auth
  error, focused on the Product Lines section with the real product
  card.
- Webhooks: replaced the create-endpoint modal with a real production
  Activity-tab screenshot (Endpoints / Event Catalog / Logs / Activity
  tabs visible, Historical Delivery Attempts stats, Recent Activity
  chart).
- Data Vault: replaced the create-store modal with the existing
  storeDesc-data-vault-4 screenshot, which shows a real store plus the
  SDK code example for getValue/setValue.
- Launch Checklist: tighter crop around the 0/6 progress card and
  Domains & callbacks section.
- Teams, RBAC, Emails, Analytics: recaptured at the same 1800 viewport
  with the same crop region so the whole catalog looks consistent.
