refactor: plan Lab path materialization

[chubes4]

Summary

• Consolidate Lab controller-side path discovery into PathMaterializationPlanner, evaluated before remote workspace mutation and consumed once by workspace staging.
• Add additive config_path_fields declarations to extension agent-runtime manifests and carry them into the runtime catalog; provider-config validation honors declared fields.
• Persist RunnerExecutionRecord transition snapshots for daemon and reverse-broker planned, running, and terminal states, including job watch/follow/cancel actions.

Fixes #7705

Planner design

The planner resolves workspace refs and aggregates provider configuration, agent-task plans and fanout, runtime components, settings, rig-declared passthrough inputs, refresh/extension sources, overlays, and rig component environment paths before staging. Workspace staging consumes its resolved argv and workspace list, eliminating the former post-remap path-setting re-scan.

Parity coverage

Existing scanner tests continue to cover each discovery source. The new planner test combines provider config, settings, and a rig passthrough path after --, preserving the #7184 class of path translation through a single pre-stage plan.

Manifest declaration schema

agent_runtimes[].config_path_fields is an optional array of dotted selectors, with [] and * support for arrays/maps. It is additive: manifests without declarations retain existing behavior.
