Scrub the maintainer's personal identifiers from the public tree

The two-model review's hygiene scan found the maintainer's username, home
network hostname and LAN addresses, an absolute checkout path, a personal
external-drive path and a personal tool reference in tracked files: the
example MCP configs under agents/, a module docstring in shared.py, the
session-DB tiering page, a benchmark constant, a workflow script, a test
docstring and the eval golden fixture's notes. None of it was a credential,
all of it was personal. Replace each with a neutral placeholder or a
home-relative path; drop the personal MCP server entry; move the archived
agent configs (which carried the same paths) to the private repository; and
fix a spec that still named the project by its old repository name.
