Summary

docs-site/docs/architecture/shared-packages.mdx listed 5 of the 13 packages under packages/, and said both apps consume all of them. This adds a row for each missing package (cli, runner, runner-protocol, sandbox-box, sandbox-contract, sandbox-cube, sandbox-daytona, sandbox-local), with the one-line summaries taken from each package's README, and keeps the table in alphabetical order.

The paragraph below the table is corrected from the package.json files. The frontend uses agent-client, agent-harness and artifact-workspace. The backend also uses artifact-formats, runner-protocol, sandbox-contract and the four sandbox packages. cli and runner are standalone tools that no app imports.

Fixes #226

How I checked it

• The table now has 13 rows, one per folder under packages/ with a package.json.
• Each "who uses it" claim was checked against backend/package.json, frontend/package.json and the package.json of each package.
• cd docs-site && bun run build and bun run doctor pass, and the built page lists all 13 packages.
• bun test scripts/agent-docs.test.ts: 5 pass.
• No em dashes in the changed text.
