Add rule: scope task lists to current repository

When a developer asks for open tasks, only return tasks from the project(s)
linked to the current git repository. Flag it if no project is linked.

+# BC MCP: Scope Task Lists to the Current Repository
+
+## Rule
+
+When a developer asks "what tasks do I have", "what are my open tasks", or any
+equivalent question about their work queue, **only return tasks that belong to
+the project(s) linked to the current git repository**.
+
+Do **not** return all tasks assigned to the developer across all BC projects.
+That produces noise from unrelated customers and hides the signal of what is
+actually in scope for the current repo.
+
+## Why
+
+A developer working in a repository is focused on that context. Showing tasks
+from other projects (other customers, other repos) creates confusion and
+increases the risk of working on the wrong thing or copying context from the
+wrong project.
+
+## Standard recipe
+
+```
+1. git remote get-url origin
+   → e.g. "https://github.com/Curabis/Wareco.git"
+
+2. List_ProjectRepositories_PAG6102904
+      filter: "gitHubRepository eq '<url>'"
+   → get projectNo(s) for this repo
+
+3. IF no projects found → STOP and flag (see "No linked project" below)
+
+4. List_ActiveTasks_PAG6102900
+      filter: "projectNo eq '<projectNo>' and taskResponsible eq '<employeeCode>'"
+   → return only tasks in this repo's project(s)
+```
+
+For developer identity (resolving `employeeCode` from git email), see
+`[[bc-mcp-find-active-task-for-branch]]`.
+
+## No linked project — flag it
+
+If step 2 returns no results, do not fall back to listing all tasks.
+Instead, surface it explicitly:
+
+> **Flag:** Dette repository (`<url>`) er ikke knyttet til et BC-projekt.
+> Opgavelisten kan ikke scopetes. Tilknyt repoet via `projectRepositories`
+> (PAG6102904) eller kontakt projektlederen.
+
+This is a data-quality issue that should be fixed, not silently bypassed.
+
+## Multiple projects on one repo
+
+If step 2 returns more than one project for the repo, query tasks from all of
+them and group the output by project.
+
+## What to show
+
+| Field | Include |
+|---|---|
+| `taskNo` | Yes |
+| `description` | Yes |
+| `status` | Yes |
+| `gitHubDevStatus` | Yes — shows In Progress / Backlog / Done / On Hold |
+| `gitHubBranch` | Yes — shows which branch the task is on |
+| `estimatedTime` / `timeLeft` | Yes — helps prioritize |
+| `expectedDelivery` | Yes — shows urgency |
+| `customerName` | Yes — context |
+
+Do not show internal system fields (`taskId`, etags, `@odata.*`).
+
+## Violations to avoid
+
+- Filtering only by `taskResponsible` without scoping to `projectNo` → returns
+  tasks from every customer the developer has ever worked on.
+- Falling back to all-tasks when the repo lookup fails → hides a config problem.
+- Returning tasks where `gitHubRepository` on the task matches (this field is
+  obsolete — always scope via the project, not the task field).
