Bump to v1.0.0 (first stable release; metadata maintenance) (#9)

Promotes dcebe to 1.0.0 to signal API stability. The MATLAB reference
implementation has been published since 2018; the Python port was
developed in 2026 and the public API (estimate_bat) is unchanged
from the 0.1.0 dev release.

Aligns pyproject.toml, python/dcebe/__init__.py __version__, and
CITATION.cff version/date-released. Adds CHANGELOG.md (was missing).
No algorithmic changes.

+# Changelog
+
+All notable changes to the `dcebe` Python package are documented here.
+This project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html)
+and the [Keep a Changelog](https://keepachangelog.com/en/1.1.0/) layout.
+
+The MATLAB reference implementation is tracked separately in this same

+## [Unreleased]

+## [1.0.0] — 2026-05-11
+
+First stable release.
+
+The MATLAB reference DCEBE has been published since 2018 (paper:
+Bendinger, Debus, Glowa, Karger, Peter, Storath, *Bolus arrival time
+estimation in dynamic contrast-enhanced MRI of small animals based on
+spline models*, Physics in Medicine & Biology 64(4), 2019). The Python
+re-implementation in this repository was developed in 2026 as a port
+of the MATLAB code; the user-facing API (`estimate_bat`) is unchanged
+from the 0.1.0 dev release.
+
+### Added
+
+- Python re-implementation of `DCEBE_estimateBAT.m` as `estimate_bat`,
+  returning an `EstimateResult` dataclass with 1-based MATLAB-compatible
+  sample units.
+- `pip install dcebe` from PyPI. Pure Python (NumPy + SciPy); no
+  compiled wheels, no Rust, no MATLAB runtime required.
+- Auto-create GitHub Release on tag push (alongside PyPI publish).
+- `CITATION.cff` with `version` and `date-released` fields.
+- README harmonised with the lab-repo family (badge block,
+  Quickstart-first ordering, "See also" section linking the five
+  sibling repos, License footer).
+
+### Changed
+
+- `LICENSE` cleaned up: non-standard "if this code is used in any
+  scientific publication, the following paper shall be cited" clause
+  removed. The LICENSE file is now pure Apache-2.0 matching the
+  declaration in `CITATION.cff` and `pyproject.toml`. The citation
+  request lives in `CITATION.cff` and the README.

Particularly intended for signals without a fast upslope, as commonly seen in small-animal data. Parameters are selected via generalised cross-validation."
