Agent Observer 0.5.0a20

Agent Observer a20 extracts Agent-native cached acquisition into the optional networking component. The Agent-owned Service 2 source uses Mesh SDK v1's generic cached publisher and a trusted lazy factory for local serving and fixed SSH publication. It also adds bounded mesh assess diagnostics.

API 2, snapshot/watch 4, Service 2 and Mesh SDK/Read/Delivery 1 remain unchanged. Core observation is Codex-only and Mesh-free; collection, provider workflows, writer, attachment/actions and clients retain independent selections.

Acceptance: 376 source tests; installed package/profile/network gates on Snap and Starship; local and actual owned SSH cached publication; independent daemon comparisons; mixed old/new readers; local CPU/PSS/FD attribution and a controlled 1512-row capacity case. Operational adoption is a following scoped gate. WSS, physical suspend and downstream UI are separate.
