Stabilize Workspace As Local View Tasks

• Research current workspace runtime, guidance, and test coverage.
• Re-anchor guidance direction in direction.md.
• Decide that generated guidance should route durable coordination to initiatives and implementation planning to repo-local changes.
• Decide that generated guidance should stop recommending workspace-level changes/ as the planning home.
• Decide that workspace update refreshes the generated guidance block for existing workspaces.
• Update workspace-planning action context so beta workspace artifacts are compatibility context, not the source of truth.
• Decide to defer normal doctor skill summaries until users need an installed-skill inventory.
• Update workspace update wording to include workspace-local guidance and agent skills.
• Define the minimal doctor/status improvement for local paths, unresolved links, and installed agent skills.
• Identify the focused code/test files for the implementation slice.
• Run the targeted workspace and artifact workflow test slice before landing implementation.
• Close out live docs wording that still framed workspaces as durable planning homes.
