Docs: link server CLI docs and list flags/env vars

[codenomadbot]

Closes #173.

What changed

• Improve top-level README.md "CodeNomad Server" section with:
  • a direct pointer to packages/server/README.md
  • a --help discovery hint
  • a per-project install/run snippet
• Expand packages/server/README.md with:
  • --help hint
  • "Install locally" section
  • additional CLI flags/env vars that exist in packages/server/src/index.ts but were missing from docs (UI + logging)
  • advanced env vars for dev update checks

Why

• Make it obvious where to look to run the web UI and discover configuration options (flags/env vars) without having to search the code.

Notes

• Docs-only change; no runtime behavior changes.

Changes needed in this PR

1. Dev releases needs its own section
2. Link server README as link in main README
3. Reduce the server launch details in main README and ensure its in server README

[codenomadbot]

Applied the requested doc adjustments and pushed an update to this PR.

What I understood

• You want dev releases called out in a dedicated section.
• The main README.md should link (as an actual markdown link) to the server README.
• The main README.md should be lighter on server launch/install details, with the full details living in the server README.

What changed

• README.md
  • Link to server docs is now a clickable link: [packages/server/README.md](packages/server/README.md).
  • Removed the longer server install/run block from the main README to keep it high-level.
  • Added a dedicated Dev Releases section with the dev package launch command.
• packages/server/README.md
  • Renamed/expanded the advanced update section into Dev Releases (Advanced) and included the dev package launch command.

Commit

• 8c24a7d docs: reorganize server and dev release docs
