docs: purge live-doc product-brand mentions; consolidate v0.1.x migration map

User-facing prose, examples, and command shapes no longer name the
deprecated qcodes integration anywhere; the only places where the old
identifiers survive are intentional search anchors for upgraders.

- README.md: replace 'previous nqctl baseline' with a neutral
  amortisation phrasing; the install / configure / embedded-Python /
  Developing sections were already qcodes-free.
- docs/quickstart_simulator.md: rewrite for the public-PyPI 0.2.0
  install path; replace the broken 'QCodes smoke' section with a real
  NanonisController example; drop the deleted trajectory monitor
  section and the dead notebook / trajectory_model.md references.
- docs/extension_workflow.md: rename the legacy 'QCodes driver' section
  to 'embedded Python API'; drop the 'CLI/QCodes' label.
- docs/architecture.md: drop the gratuitous '(no qcodes dependency)'
  parenthetical from the controller component description.
- CHANGELOG 0.2.0: restructure the entry so the narrative no longer
  uses the qcodes brand, and consolidate every v0.1.x symbol / package
  / class name that an upgrader might grep for into a single dedicated
  Migration map at the bottom of the 0.2.0 section.
- Delete PLAN.md (obsolete 0.1.x bridge-thesis design doc that no
  longer matches the v0.2.0 product shape).
- Delete the obsolete private-index release infrastructure that the
  v0.1.x flow assumed: docs/release_private_index.md,
  .github/workflows/publish-private.yml, and the three contract tests
  that pinned the old shape (test_release_docs, test_release_checklist_
  contract, test_publish_workflow_contract). v0.2.0 ships to public
  PyPI; the old runbook was misleading.
- Rename tests/test_qcodes_driver.py -> tests/test_controller.py and
  tests/test_qcodes_extensions.py -> tests/test_controller_extensions.py;
  rename the lone test_qcodes_methods... function inside; drop the
  dead 'qcodes is not installed' skip markers in test_controller.py
  and test_simulator_integration.py (we no longer depend on that
  package).
- Whitelist test_controller.py and test_smoke.py in .gitignore so CI
  picks them up alongside test_controller_extensions and test_daemon.

Verification: ruff/black/mypy all green; pytest 82 passed + 1
simulator-gated skip locally.

 ## [0.2.0] - 2026-06-30
 
-This release renames the project and is intentionally **breaking**. The
-package is now `nspmctl` (was `nanonis-qcodes-controller`) and the CLI
-command is now `nspmctl` (was `nqctl`). All command names, argument shapes,
-and JSON response schemas of the surviving subcommands are preserved.
+This release rebuilds the project around a single thesis: a thin, fast
+CLI over `nanonis-spm` for agent-driven Nanonis SPM controller
+automation. It is intentionally **breaking**. The package, CLI command,
+and internal API surface are all renamed; everything not on that
+critical path was cut. Command names, argument shapes, and JSON
+response schemas of the surviving subcommands are preserved.
 
 ### Breaking changes
-- Renamed PyPI package `nanonis-qcodes-controller` -> `nspmctl`.
-- Renamed CLI command `nqctl` -> `nspmctl`.
-- Renamed Python package `nanonis_qcodes_controller` -> `nspmctl`.
-- Renamed internal subpackage `nanonis_qcodes_controller.qcodes_driver` ->
-  `nspmctl.controller`.
-- Removed Python class `QcodesNanonisSTM`. The replacement
-  `nspmctl.controller.NanonisController` has the same constructor /
-  method surface but no qcodes Instrument base.
-- Removed the qcodes runtime dependency entirely; the `[qcodes]` extra is
-  gone. `nanonis-spm` is now a hard runtime dependency (it used to live in
-  the `[nanonis]` extra).
-- Removed the trajectory subsystem entirely. The following `nqctl`
-  subcommands no longer exist (the agent contract on get/set/ramp/act
-  payloads also no longer contains the `"trajectory"` block):
+- Renamed PyPI package, Python package, CLI command, and instrument
+  class. See the migration map at the bottom of this entry.
+- The previous embedded instrument wrapper no longer derives from an
+  external framework base class; it is now a plain class with the same
+  constructor and method surface.
+- The heavy optional framework integration that used to back the
+  embedded driver is gone; `nanonis-spm` is now a hard runtime
+  dependency (previously gated behind an extra).
+- Removed the trajectory subsystem entirely. The following CLI
+  subcommands no longer exist (the agent contract on
+  `get`/`set`/`ramp`/`act` payloads also no longer contains the
+  `"trajectory"` block):
   - `trajectory tail`, `trajectory follow`
   - `trajectory action list`, `trajectory action show`
   - `trajectory monitor config show|set|clear`

+### Migration from v0.1.x

+| Old (v0.1.x)                                                            | New (v0.2.0)                                                  |
+|-------------------------------------------------------------------------|---------------------------------------------------------------|
+| `pip install nanonis-qcodes-controller`                                 | `pip install nspmctl`                                         |
+| `nqctl <subcommand>`                                                    | `nspmctl <subcommand>`                                        |
+| `import nanonis_qcodes_controller`                                      | `import nspmctl`                                              |
+| `from nanonis_qcodes_controller.qcodes_driver import QcodesNanonisSTM`  | `from nspmctl.controller import NanonisController`            |
+| `nanonis_qcodes_controller.config.load_settings`                        | `nspmctl.config.load_settings`                                |
+| `nanonis_qcodes_controller.client.create_client`                        | `nspmctl.client.create_client`                                |
+
+The new `NanonisController` keeps the same constructor signature and
+method names; the only required edit is the import line.
