build(framework): make ecu-framework pip-installable

- Add pyproject.toml (hatchling backend, version 0.1.0, name ecu-framework).
  Runtime deps split out from requirements.txt; test extras and the
  Melexis-transitive bundle are opt-in.
- Add CHANGELOG.md (Keep-A-Changelog format), seeding [Unreleased] with the
  installable shift and a [0.1.0] entry for the existing baseline.
- ecu_framework/__init__.py: resolve __version__ from importlib.metadata
  with a "0.0.0+local" fallback for source checkouts. Add power and
  flashing to __all__ and the docstring (previously stale).
- Drop per-subpackage __version__ from lin/ and power/. A single
  pyproject.toml version is the source of truth; subpackage-level
  __version__ strings drift and nothing consumed them.

+# Changelog
+
+All notable changes to **ecu-framework** are documented in this file.
+
+The format follows [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+The single source of truth for the current version is `[project.version]` in
+`pyproject.toml`; at runtime it is exposed as `ecu_framework.__version__`.
+
+## [Unreleased]
+
+### Added
+- `pyproject.toml` — the framework is now `pip install -e .`-able.
+- Top-level `ecu_framework.__version__` is read from installed package metadata
+  via `importlib.metadata`, with a `"0.0.0+local"` fallback for source checkouts
+  that have not been `pip install`-ed.
+
+### Removed
+- Per-subpackage `__version__` strings on `lin`, `power`, `flashing`. Versioning
+  is centralized on the distribution; subpackages no longer carry their own.
+
+## [0.1.0] - 2026-05-14
+
+Initial tagged baseline. The framework already supports:
+
+- LIN abstraction (`LinInterface`, `LinFrame`) with mock, MUM, and deprecated BabyLIN adapters
+- Owon PSU control with cross-platform serial-port resolution
+- UDS-over-LIN flashing scaffold (`HexFlasher`)
+- Pytest plugin: requirement traceability, HTML report metadata, CI summary
+- LDF parsing helpers and generated per-frame `pack`/`unpack` APIs
+- Raspberry Pi deployment recipe and a Docker image for mock-only CI
