v0.85.0: self-update reworked — in-guest pull + agent swap (Phase 1)

Browse Source 
Replaces the dead in-container docker-compose self-update (composePath doesn't
exist in the LXC guest). The controller now docker-logins+pulls the target image
in-guest (shared socket, its registry token), then delegates the container swap to
the host agent (agentapi.SwapController -> POST /controller/swap), which owns the
restart + health-verify + rollback. Removed performUpdate compose flow /
updateComposeFile / composePath. NewUpdater takes an AgentSwapper. DryRun reports
agent_reachable + pull_capable. UI button + poll unchanged; latest-only.

Tests: up-to-date no-op / pull-fail agent-not-called / happy pull-then-swap /
no-agent unavailable.
