Fix peewee model attributes missing from generated docs (#86)

[levon003]

Fixes #86.

Root cause

The skip_inherited_members autodoc-skip-member callback in docs/conf.py was written assuming the hook receives the class as obj and checks name in cls.__dict__. Sphinx actually passes the member itself as obj, so name not in obj.__dict__ was true for essentially every member and the callback skipped it.

This was broader than the reported symptom: it silently suppressed nearly every class member site-wide, not just peewee fields. EvalRunner, for instance, documented only 1 member instead of its 8 methods. The peewee models just made it most visible since all their content is field attributes.

Changes

• Replace the buggy callback with skip_peewee_internals, which surfaces all real fields/methods and only filters genuine peewee-metaclass noise: the per-model DoesNotExist exception and the <fk>_id aliases that duplicate each foreign key (detected via name != field.name, since the alias shares the FK's Field object). Real *_id fields like tool_call_id are kept. Inherited members stay excluded via the existing inherited-members: False.
• Add numpydoc_show_class_members = False to drop numpydoc's per-class summary tables. These duplicated autodoc's member docs and listed ~45 inherited peewee.Model methods (save, select, bulk_create…) as noise on every model page (pre-existing). It also eliminates the "stub file not found" warnings those tables' :toctree: would emit.
• Expand the DEVELOPMENT.md docs-building section: installing the docs dependency group, output location, the sphinx-autobuild server, the make docclean caching gotcha (essential for config changes to take effect), scanning warnings, and a note on the peewee/autodoc interaction.

Verification

Clean rebuild (make docclean html):

• Metric documents all 21 fields; EvalRunner all 8 methods
• No DoesNotExist / FK-alias / inherited-method noise
• Build warnings down from 35 → 27 (remaining are pre-existing docstring-markup issues unrelated to this fix)
