* feat(providers): add native options and exact MCP grants
Keep provider policy in provider-owned schemas so unattended Hub runs can grant only requested tools from injected MCP servers. Preserve the native resolved sandbox policy when a workflow override is present, including configured writable roots.
* test(hub): verify real provider tool policy
* test(app): avoid pinning transient restart status
* feat(hub): pass execution MCP servers to agents
Hub-owned execution capabilities need to reach provider sessions without becoming part of outward agent snapshots. Keep the configuration daemon-private so provider recovery continues to work.
* fix(hub): protect daemon MCP namespace
Hub execution MCP configuration must not replace the daemon-owned Paseo server. Validate only after owned-record lookup so idempotent replay remains stable while new launches fail before provider or durable state creation.
* fix(agent): reject unsupported MCP launches
* fix(agent): scope MCP support guard
* fix(agent): redact MCP metadata from wire payloads
* fix(agent): validate MCP support on restored sessions
* fix(session): rehydrate MCP config on resume
* fix(session): resume newest matching agent record
* fix(session): restore archive state after failed resume
* feat(server): control Hub execution lifecycle
* fix(server): archive only execution-owned worktrees
* fix(server): serialize Hub execution control after create
* test(server): compare Hub worktree paths canonically
* fix(server): make absent Hub controls idempotent
A Hub can own an execution before agent creation materializes. Treating an absent daemon-scoped record as already stopped or archived lets finality complete without revealing or affecting another daemon's execution.
