fix(packaging): give axis-init and the python SDK findable listings

Same defect just fixed on axis-server, left in place on the other two
published artifacts. Neither carried a repository link, so a reader who
found the package had no route to the source, and the keywords were
terms nobody searches ("governance", "context") rather than the ones
people actually browse (mcp, claude-code, cursor).

axis-init's description said "initialize axis context in your project",
which does not tell a reader what it writes or why they would run it.

The python SDK's url still pointed at VirSanghavi/shared-context. GitHub
301s renamed repositories so it resolved, but it stops resolving the day
anything else claims that name, and project_urls gives PyPI the sidebar
links it renders.

Licenses left untouched on purpose: setup.py declares MIT while the root
LICENSE is AGPL-3.0, and reconciling that is a call for Vir, not a
packaging cleanup.
