Add Cloud Agent development environment

[eulestadt]

Summary

Sets up a Cloud Agent development environment for this repository, which previously had no dependency or environment configuration. The project has two runnable components:

• A Python figure generator (ebv_lytic_expression/plot_yuan2006_timecourse.py) that reads the curated Yuan 2006 CSV and renders a matplotlib PNG of EBV lytic RNA kinetics.
• A static web app (ebv_lytic_expression/web/) — an interactive SVG chart of the same timecourse.

Changes

• Add ebv_lytic_expression/requirements.txt pinning matplotlib, numpy, and pandas.
• Add .cursor/environment.json (repo-managed, highest-precedence config that follows branches/PRs):
  • install refreshes Python dependencies (idempotent).
  • a web terminal serves the static app on 0.0.0.0:8000.
  • exposes port 8000.
