Cardano Updates

The default-provider install was gated behind the u5c feature, but the
multi-provider panic affects any TLS path that relies on rustls' process
default (gcp/elasticsearch/hydra/mithril via reqwest/tungstenite), not just
u5c. Make rustls a non-optional dep and run the install for every build so no
feature combination can hard-crash on the first TLS handshake. The install is
idempotent (the Result is ignored), so it's a no-op when a provider is already
set, and the AWS SDK still uses its own provider.

With OIDC the credential env is set by configure-aws-credentials; run-test.sh
now forwards any AWS_* vars present rather than hardcoding
AWS_ACCESS_KEY_ID/AWS_SECRET_ACCESS_KEY/etc. Drops the now-unused KIND env.

The AwsS3 sink stores raw block CBOR and only accepts Record::CborBlock;
the ParseCbor filter (copied from a stale example) turned it into a
ParsedBlock, so the sink failed with 'config error'. S3 takes the CborBlock
straight from the source — no parse filter. (SQS/Lambda keep SplitBlock +
ParseCbor since those sinks consume per-tx ParsedTx records.)

The OuraE2ETest role's trust path no longer matches static IAM user keys (the
`security token invalid` failures). Switch the aws legs to keyless OIDC:
add `id-token: write` and drop `aws-access-key-id`/`aws-secret-access-key` so
configure-aws-credentials uses AssumeRoleWithWebIdentity.

Requires (AWS side): an IAM OIDC provider for token.actions.githubusercontent.com
and a trust policy on OuraE2ETest allowing this repo's workflow.

Add CardanoKit, a Swift library for Cardano wallet and transaction
support in iOS/macOS apps, under the SDKs & Libraries category.

Also add `swift` to the language property taxonomy (its first use).

The n2c legs depended on a placeholder Demeter dmtrcli socket port-forward
that isn't wired up yet. Remove them and their artifacts (the two configs, the
setup/stop dmtrcli scripts, the socket mount and `continue-on-error` guard) so
the suite is all-green and fails honestly on the remaining n2n/aws/u5c legs.
Will reintroduce once the dmtrcli infra is in place.

Wallet-aware connect CTA + polished wallet/UTXOS connector

Update cip-179 to V4

- Detect installed wallet providers; when none are present, lead with a
  friendly "Get Started with Multisig using UTXOS" CTA (with an escape hatch
  to open the full picker) so non-crypto users don't hit a wallet wall.
- When a wallet extension is detected, keep the normal flow but stop
  recommending UTXOS specifically: drop the "Recommended" badge/tint and the
  homepage "New to crypto? Try UTXOS" box.
- Redesign the connect dropdown — cleaner UTXOS card (brand tile, network
  toggle + connect row) and wallet rows that show each wallet's real icon.

Resolves #5

SEO:
- Central src/lib/seo.ts; route-aware <Metatags> (titles, canonical, OG,
  Twitter, robots noindex, JSON-LD) hoisted out of the ssr:false boundary
- /robots.txt + /sitemap.xml; static public/og-image.png (+ generator script)
- NEXT_PUBLIC_SITE_URL env; favicon/manifest fixes; drop duplicate metatags

Landing & public pages:
- Live mock-data feature previews replace PNG screenshots (auto-track the UI)
- Unified SiteFooter across all public routes; hero polish; /features refresh
- Multisig 3-of-5 signing explainer; animated feature-card SVG icons
- API-docs intro; reconcile feature set (drop orphan "chat", add staking)

Background:
- Layered animated aurora + WebGL frosted-marble hero (cursor parallax,
  domain-warped veins); reduced-motion-safe

Fixes:
- Footer/min-h-screen flex-shrink overlap in RootLayout
- Extract GovernanceTypeChip to a shared, lightweight module
