Add planning baseline: BC, SA, PP and MIL-001 to MIL-003

Draft and accept the Business Case, Stakeholder Analysis (S01-S03) and
Project Plan for the Day 15 coffee machine assignment. Add three
milestones with 17 tasks, synced to the git host as Milestones 40-42
and Issues #1-#17. Register PP and MIL in the artifact registry and set
the PO language to en.

No issue closed: planning only, no code changed.

+
+## Purpose
+
+Decide whether the project is tested, documented and ready to share.
+
+## Deliverable
+
+pytest suite, Doxygen output, finished README, and repository description and topics on the git host.
+
+## Go / No-Go Criteria
+
+| # | Criterion (objectively checkable) | Go | No-Go |
+| --- | --- | --- | --- |
+| 1 | `python -m pytest` passes with all tests green | All pass | Any failure |
+| 2 | `doxygen Doxyfile` runs without warnings on `src/` | No warnings | Warnings |
+| 3 | Repository has a description and at least 3 topics | Set | Missing |
+| 4 | `pyproject.toml` lists no runtime dependencies and `.env` is not imported or tested | Confirmed | Violated |
+
+## Dependencies
+
+| Depends on | Reason |
+| --- | --- |
+| MIL-002 | Behaviour must exist before it is tested and published |
+
+## Traceability
+
+| Business Case objective / KPI / user story | Reference |
+| --- | --- |
+| Objectives 3, 4, 5 | [BC-001] |
+
+## Ownership

+| Role | Stakeholder ID (SA) |
+| --- | --- |
+| Owner | S01 |
+| Approving reviewer | S01 |
+
+## Target Date
+
+2026-10-12 — within the short course-assignment timeline in [BC-001].
+
+## Tasks
+
+| # | Task | Summary | Needs its own Use Case/User Story? | Reference |
+| --- | --- | --- | --- | --- |
+| 1 | Write tests for resources and report | pytest tests for `report` output and `is_resource_sufficient` with sufficient and insufficient resources. | No | Objective 3 |
+| 2 | Write tests for coins and transactions | pytest tests for `process_coins` (mocked input), refund, exact payment, change and profit updates. | No | Objective 3 |
+| 3 | Write tests for make_coffee and main loop | pytest tests for resource deduction and for `off`, `report` and invalid input handling through mocked `input`. | No | Objective 3 |
+| 4 | Generate and check Doxygen output | Run `doxygen Doxyfile`; fix undocumented or malformed comments. | No | Objective 4 |
+| 5 | Set repository description and topics | Use the git host API with the token in `.env` (personal use only, never imported by the project) to set the description and topics, after the user confirms the exact text. | No | Objective 5 |
