docs(content): PR A — sidebar IA fix + community page

- Expose four orphan operations files in the sidebar (deployment,
  register-a-node, release-checklist, migration-from-static-docs were
  already on disk but not listed).
- Add a Community page sourced from the live landing's people/funding
  blocks, with hosted-nodes pointer and event log.

Phase 3 of the legacy open-pulse-documentation port. Smallest blast
radius first; concept pages (metadata, graph-data, metrics) and the
contributor guide follow in subsequent PRs.

+# Community
+
+Open Pulse is built in the open by **SDSC** and **EPFL Open Science**, and
+is meant to be reusable by any institution or research programme that
+wants to surface the activity around its open-source software outputs.
+
+## About the project
+
+Open Pulse automates the discovery and monitoring of open-source software
+produced by a research institution and makes community vitality and
+engagement visible and measurable. Traditional metrics — paper citations,
+GitHub stars — only capture a fraction of open-science impact; many
+valuable projects stay invisible because they are niche, early-stage, or
+low-visibility. Open Pulse aims to map and surface those hidden
+contributions across the full continuum of community engagement.

+## Institutions and funding
+
+A project by **SDSC** and **EPFL**, funded by **swissuniversities** and
+the **ETH Board**.
+
+A
+[preliminary GitHub analysis](https://github.com/EPFL-Open-Science/EPFL_OS_Analysis)
+sponsored by EPFL Open Science seeded the work that became Open Pulse.
+
+## Hosted nodes
+
+Anyone running an Open Pulse instance can register it as a hosted node
+so the project landing surfaces a discoverable card for it. See
+[Register a node](../operations/register-a-node.md) for the schema and
+the browser-only node-builder form. The first listed node is
+[openpulse.epfl.ch](https://openpulse.epfl.ch), the EPFL instance.
+
+## Events
+
+- **Open Pulse Mini-Hackathon** — November 2025. Hands-on workshop on
+  community health, license impact and cross-institutional collaboration
+  patterns using Open Pulse data.
+- **Open Pulse Webinar** — January 2026. Introduction to the
+  architecture, the data access surfaces (SPARQL, Cypher, REST) and
+  research use-cases.
+
+## Get involved
+
+- **Code** — open an issue or PR at
+  [sdsc-ordes/open-pulse](https://github.com/sdsc-ordes/open-pulse).
+- **Run your own node** — see

+- **Share research** — Jupyter notebooks, papers and case studies built
+  on Open Pulse data are welcome.
