feat: Add missing E2B-compatible sandbox lifecycle APIs

[AiRanthem]

Background

sandbox-manager implements core E2B lifecycle endpoints for create, list v2, get, delete, pause, resume, connect, timeout, and snapshots.

The current E2B platform API and SDK include additional lifecycle-related surface that is not registered or not represented in the request/response models, including refresh and lifecycle configuration/status fields.

Issue Type

Feature request

Relevant Code

• pkg/servers/e2b/routes.go registers create, list v2, get, delete, pause, resume, connect, timeout, and snapshots, but no POST /sandboxes/{sandboxID}/refreshes.
• pkg/servers/e2b/models/sandbox.go models autoPause, but not the SDK lifecycle / auto-resume fields.
• pkg/servers/e2b/pause_resume.go and pkg/servers/e2b/timeout.go contain the current pause, resume, connect, and timeout behavior.

Notes

Related E2B-compatible surface includes:

• POST /sandboxes/{sandboxID}/refreshes
• lifecycle / auto-resume fields on POST /sandboxes and sandbox detail responses
• lifecycle visibility APIs such as sandbox logs and metrics, if the project wants parity with the current E2B platform API.
