Subject: [PATCH 1/3] fix(cloud): back the MCP session Durable Object with
 SQLite

The MCP session DO now extends the Cloudflare Agents `McpAgent` base, which
stores its state in SQLite. apps/cloud still had the original `McpSessionDO`
class on the key-value backend (`new_classes`), and Cloudflare cannot convert a
live class to SQLite in place, so every session 500'd with
"This Durable Object is not backed by SQLite storage".

Session state is ephemeral, so delete the old KV class and create a new
SQLite-backed class (`McpSessionDOSqlite`) in migration v2, repointing the
`MCP_SESSION` binding. The DO is addressed by binding + idFromName, so the
rename is transparent at runtime. host-cloudflare was already on
`new_sqlite_classes`, so only cloud was affected.

Subject: [PATCH 3/3] fix(cloud): recreate MCP session DO as SQLite via
 migration (revert class rename)

Same-name delete+recreate (v2 delete, v3 new_sqlite) keeps the McpSessionDO
binding and worker export unchanged, avoiding the rename that left the deleted
KV class still exported. Reverts the server.ts/app.ts rename from the prior
attempt; the only code-level change is the wrangler migration.
