feat(agency): complete WP-0002 Part 3 — E2E tests, docs, sys-medic cross-refs, bugfix

T25: add tests/test_e2e_agency_framework.py — 16 E2E tests covering the full
memory lifecycle (init, show, brief, clear) and protocol list/show commands.

T26: replace agency-framework.md protocols placeholder with full documentation —
location convention, frontmatter schema, CLI reference, sys-medic memory
extensions, and protocols table.

T27: add Related Documents footer to agent-sys-medic.md linking to the k3s
protocol runbook, ADR-002, ADR-003, and agency-framework.md.

Fix: rename CLI command function list() → list_agents() to stop it shadowing
Python's built-in list(). The shadow caused memory_brief() to invoke the
agent-list command instead of constructing a list from dict keys, producing
the agent list as output on every `memory brief` invocation.

All 27 WP-0002 tasks complete. Test suite: 51 passed, 1 skipped.
