chore: add .coderabbit.yaml pinning Docstring Coverage to warning

[hyperpolymath]

Summary

Adds .coderabbit.yaml pinning CodeRabbit's Docstring Coverage pre-merge check to mode: warning (threshold 80) and enabling the docstrings finishing touch.

Why

This repo's effective main rules require the CodeRabbit status context (measured 2026-10-01 via rules/branches/main), so an error-mode Docstring Coverage check would make PRs here unmergeable at today's baseline. The level is pinned explicitly (an estate decision) rather than left to the vendor default.

Verification

• Key paths reviews.pre_merge_checks.docstrings.{mode,threshold} and reviews.finishing_touches.docstrings.enabled checked against the fetched https://coderabbit.ai/integrations/schema.v2.json (structural check: keys present in schema, mode in enum, threshold a number in [0,100], enabled boolean). No path differences from the intended layout.
• SPDX header MPL-2.0 on line 1.
• Plain YAML; parses with yq.
