Worktree, container, and sandbox IDs now flow uniformly from a persisted
TaskEnvironment back into LaunchAgentRequest through a single helper. This
gives Sprites session-to-session reuse the same first-class treatment that
Docker already gained from the GitHub-token-injection PR, and lets a fallback
launch refresh the environment row instead of leaving stale IDs in the DB.
- applyExistingEnvironment propagates WorktreeID, ContainerID (via metadata),
and SandboxID (as sprite_name metadata) onto the launch request
- persistTaskEnvironment refreshes those IDs when the executor ends up
creating new resources (e.g. the previous container was pruned)
- extractSandboxID lifts the sprite identifier out of executor response
metadata so it can be persisted on the TaskEnvironment row
