New Mintlify documentation site in a top-level docs/ directory, ported from the Astro docs content in frontend/docs/src/content/docs/ and corrected against the current repo. The Astro site is untouched in this PR. Validated with npx mint validate (build validation passed) and npx mint broken-links (no broken links).

Fixes #37

Content corrections applied while porting

• Removed the Docker install tab: ghcr.io/synthetic-sciences/openscience does not exist (Docs quickstart documents a Docker image that doesn't exist #37). Marked Mise as community-maintained and untested.
• Install one-liner is curl -fsSL https://openscience.sh/install | bash; npm is npm install -g @synsci/openscience; launcher is npx synsci.
• Every $schema example now uses https://openscience.sh/config.json (was syntheticsciences.ai/config.json).
• The built-binary dev path is ./backend/cli/dist/@synsci/openscience-<platform>/bin/openscience; repo layout documented as frontend/ backend/ tooling/ with main as the default branch.
• Atlas page now describes the two credential stores accurately: openscience auth login keys stay local in auth.json and are never uploaded; openscience connect login stores a thk_ session key and pulls dashboard-connected credentials down; local keys win over synced ones; the spend toggle (billing.llm/billing.compute, managed vs byok) governs wallet gating, not which key is used.
• Documented the connect (login/status/sync/devices/logout) and billing (show/topup) CLI commands, which were missing from the old CLI reference.
• Dropped the desktop-app troubleshooting section (no desktop app ships from this repo) and the unverifiable Discord link.
• GitHub links normalized to https://github.com/synthetic-sciences/openscience; docs cross-links resolve under https://openscience.sh/docs/.

To go live

• Connect the repo in the Mintlify dashboard with docs/ as the content directory (branch main after merge)
• Point the openscience.sh /docs rewrite at the Mintlify deployment
• Verify https://openscience.sh/docs renders and cross-links resolve
