chore: repoint every repository URL at sethbang/venice-py

[sethbang]

Phase 5 — the last step of the venice-ai → venice-py rename. The repo is now sethbang/venice-py; this lands the URLs.

Why the rename came first

GitHub redirects old → new, never new → old. So sethbang/venice-ai URLs kept working right up to this commit, while sethbang/venice-py URLs would have 404'd before it. Renaming first meant nothing was broken in between; sweeping first would have.

What changed

69 references across 10 files, plus:

• docusaurus.config.ts — projectName and editUrl
• the two git clone … && cd instructions
• the README banner (raw.githubusercontent.com) and the codecov badge
• pyproject.toml Homepage / Repository / Issue Tracker / Changelog — these are what PyPI displays, and they update with the next release
• publish-testpypi.yaml's header comment recording the registered repo name

Why a lookahead, not a substitution

sethbang/venice-ai(?![-\w])

sethbang/venice-ai is a prefix of three sibling repos under this owner — venice-ai-rc, venice-ai-priv, venice-ai-streamlit-demo. A plain sed rewrites the archive guard in ci-validation.yaml:

if: github.repository != 'sethbang/venice-ai-rc'      # correct
if: github.repository != 'sethbang/venice-py-rc'      # what a naive sweep produces

That fails silently — the codecov upload just starts running on the private archive. Guarding only -rc wouldn't have been enough either; the character class covers the whole family. Verified unchanged.

What deliberately still says venice-ai

Because that is what it means, not because it was missed. All counted before and after the sweep:

	count
sethbang/venice-ai-rc (archive guard)	1
@venice-ai/x402-client (npm, different registry)	3
venice-ai-redis-node-* (docker containers)	5
venice-ai-docs (live Cloudflare Pages project)	2
legacy skill dir names (venice-ai-multimodal / -production / -x402)	16
pip install venice-ai (the old distribution name)	11
venice-ai<2 (v1 exists only under the old name)	4
venice-ai-test (a User-Agent literal in a VCR test)	2

Verification is tracked-files-only, matching what the sweep rewrites — untracked local files legitimately still say venice-ai and aren't its business.

Publishing is unaffected

Both publish workflows already guard on github.repository_owner == 'sethbang', so neither silently skips under the new name. A second Trusted Publisher for sethbang/venice-py was registered on both PyPI and TestPyPI before the rename, with the existing entries left live — those get removed only after a TestPyPI rc dispatch proves the chain.

Verification

make format-check, pyright, and the Docusaurus build under onBrokenLinks: 'throw' (82 documents) all clean. The sweep's own verifier compares before/after counts for every non-target and exits 1 on any drift — exercised on both paths, including deliberately removing the lookahead to confirm it catches the corrupted guard.
