docs: rename wren-engine package references to wrenai

[PaulChen79]

Summary

The wren CLI Python package is now distributed as wrenai on PyPI; the previous wren-engine package is frozen at 0.6.x and deprecated. This PR sweeps every live docs and skill-metadata reference so that install instructions, SDK runtime-dep notes, the architecture page, and the skill bundle metadata all match the new name. The previous rename pass missed a handful of stragglers — this finishes the job.

What changed (11 references across 7 files)

A. Docs — install commands & runtime-dep references

File	Change
docs/core/guides/refine.md	three pip install "wren-engine[...]" lines → wrenai[...]
docs/core/sdk/langchain.md	runtime-dep note + dependency table cell
docs/core/sdk/pydantic.md	runtime-dep note + dependency table cell
docs/core/reference/architecture.md	"The wren-engine Python package…" sentence

B. Skill bundle metadata (consistency with the rest of the skills, which already use wrenai)

File	Change
skills/AUTHORING.md	example frontmatter author: wren-engine → wrenai
skills/wren-dlt-connector/SKILL.md	frontmatter author: wren-engine → wrenai
skills/index.json	bundle "name": "wren-engine" → "wrenai"

Intentionally left unchanged

README.md:28 (announcement that the old Canner/wren-engine repo is archived) and core/wren/README.md:226–253 (the package-rename migration guide itself) reference the old name as part of historical context — touching them would obscure the migration story. Verified by post-edit grep.

Test plan

• grep -rnE 'wren-engine' docs/ skills/ returns no hits outside the two intentionally-kept historical references in README.md and core/wren/README.md.
• pip install "wrenai[memory]" works (matches the wrenai package on PyPI).
• skills/index.json still parses as valid JSON and npx skills add Canner/WrenAI --skill wren-onboarding continues to resolve.

Poem

🐰 A whisper through the warren spreads so fast,
From wren-engine old to wrenai at last!
The docs now gleam with names so bright and true,
Skills metadata wears wrenai's fresh new hue.
What's in a name? A rebrand's gentle touch,
That makes the future matter quite so much! ✨
