chore(release): 2.8.0

[chaoming0625]

Release 2.8.0

Bumps brainpy.__version__ to 2.8.0 and adds the 2.8.0 changelog section.

Version 2.8.0 is a broad correctness, quality, and maintainability release
covering the 37 commits since V2.7.8:

• Audited correctness sweep across neuron/synapse dynamics, integrators,
  the math/object-transform layer, dnn layers, optimizers & losses, analysis,
  and the runners — each backed by regression tests.
• Static typing: core utility annotations, PEP 561, and a new mypy CI gate (Add typing for core utils, enable PEP 561, add mypy CI #834).
• Test-suite overhaul: coverage ~84% → 92%+ (test: comprehensive coverage tests for brainpy/ (84% → 92%+) #836); tests co-located as
  <module>_test.py (test: co-locate tests as <module>_test.py and remove tests/ trees #832).
• Reduced duplication: reuse braintools (init/metric/surrogate) and
  brainstate transforms (Reuse braintools.init / braintools.metric in brainpy.initialize & losses #835, Reuse braintools.surrogate; remove duplicate brainpy.math.surrogate #833, Fix CI: replace remove_vmap with brainstate.transform.unvmap #831).
• Docs & examples repaired and refreshed (docs: convert public-API docstrings to NumPy style + enforce convention #856, fix(docs,inputs,rates): repair docs notebooks + Hz-input & RNNCell.reset(batch_size) bugs #857, fix(examples): repair 6 broken example scripts (API drift, data path, channels) #858).

Full details in changelog.md (## Version 2.8.0).
