feat: Claude Code Monitor — lanes, pipelines and a merged workspace

Internal SmartGift build of a Claude Code monitoring dashboard.

Lanes: a durable unit of parallel agent work, one per working directory,
tracked across session restarts. Managed lanes are git worktrees the
dashboard provisions and can reset or remove behind a three-check destroy
guard and a counted preflight; adopted lanes are directories you already
own and are never destroyable.

Pipelines: a lane moves through pipeline stages. A stage the agent declares
with evidence renders green; a stage inferred from the tool-event stream
renders dashed amber and never counts as done. Detection is forward-only
within a 30-minute window, and never writes the declared stage.

Workspace: one page at /run with a lane grid, the selected lane's pipeline,
and a full Claude console behind a disclosure.

+# MCP Operations
+
+Use this skill whenever work touches `mcp/` behavior or MCP host integration.
+
+## Core workflow
+- Confirm dashboard API is running (`/api/health`).
+- Confirm MCP server build status.
+- Validate env flags for mutation/destructive modes.
+- Verify host configuration path and command.
+
+## Safe operations policy
+- Default to read-only mode (`MCP_DASHBOARD_ALLOW_MUTATIONS=false`).
+- Enable mutations only for explicit admin tasks.
+- Enable destructive mode only transiently and require explicit confirmation token.
+
+## Required verification for code changes
+- `npm run mcp:typecheck`
+- `npm run mcp:build`
+
+## References
+- Host config examples: `references/host-config.md`
+- Operations runbook: `references/runbook.md`

+# MCP Host Config
+
+## Command
+- `node`
+
+## Args
+- Absolute path to `mcp/build/index.js`
+
+## Example env
+- `MCP_DASHBOARD_BASE_URL=http://127.0.0.1:4820`
+- `MCP_DASHBOARD_ALLOW_MUTATIONS=false`
+- `MCP_DASHBOARD_ALLOW_DESTRUCTIVE=false`
+- `MCP_LOG_LEVEL=info`
+
+## Common mistakes
+- Relative path to MCP build entry.
+- Dashboard not running while MCP starts.
+- Mutating tools used while mutation flag is false.

+# MCP Runbook
+
+## Read-only daily mode
+- Keep both mutation flags false.
+- Use read tools for observability and reporting.
+
+## Admin mode
+- Set `MCP_DASHBOARD_ALLOW_MUTATIONS=true`.
+- Run maintenance/pricing operations.
+- Reset mutation flag to false after completion.
+
+## Destructive mode
+- Set both mutation and destructive flags true.
+- Execute destructive command only with explicit confirmation token.
+- Immediately disable destructive flag after operation.
+
+## Verification commands
+- `npm run mcp:typecheck`
+- `npm run mcp:build`
