Build durable agent collaboration, replies, and direct messages

[NarwhalChen]

Summary

• move agent collaboration execution behind a durable Electron-main Agent Host with persisted jobs, explicit lifecycle events, identity fences, and no replay of interrupted provider actions
• add first-class message replies across storage, rendering, projection, routing, and the native workspace:send_message tool
• add deterministic private agent DMs with a sidebar entry point and a DM-only context inspector that separates injected context, discoverable channels and tools, runtime state, and opaque provider-owned state
• route channel mentions and open-floor offers through the Host while preserving background delivery and conversation-specific typing state
• fail direct jobs when the provider stream errors or finishes without actually sending a workspace message, instead of reporting a false completion
• tolerate storage-free Web Bridge test environments while retaining tab-stable client ids in real renderers

Verification

• pnpm --filter @convera/app test — 79 files passed, 495 tests passed, 1 real-provider integration test skipped by default
• pnpm --filter @convera/app lint — 0 errors, 10 existing hook warnings
• pnpm --filter @convera/app format
• pnpm --filter @convera/app exec tsc --noEmit --pretty false --skipLibCheck
• pnpm --filter @convera/app automation:typecheck
• Web Bridge regression test passed under Node 24.4.1, matching the failing macOS runner major version
• push hook reran formatting, lint, and the complete Vitest suite successfully

Real Electron automation

Ran the packaged Electron app through the repository atomic automation MCP with an isolated profile and a real Codex agent only; Claude was not executed.

• Sage configured for codex-cli / gpt-5.6-sol used workspace:send_message and wrote DM_AUTOMATION_OK into its private DM
• reply affordance preserved and displayed the quoted Sage message, including the jump-to-parent target
• the same stable DM and durable Host state survived application relaunch
• background work continued after navigating away; public #general showed neither the DM-only Context control nor Sage typing from the private conversation
• a later Codex turn that emitted no workspace message was recorded as failed with The agent completed a direct offer without sending a message, validating the false-success guard

Boundaries

• provider-native resumed history, provider hidden prompts, and sandbox internals intentionally remain opaque to the renderer
• no real Claude run was performed
• .planning/ and local automation profiles/artifacts are not part of this PR
