Loki Mode

Added

• loki mcp: launch the Loki Mode MCP server reliably from any project
  directory. Fixes three independent launch blockers a fresh npm consumer
  hit: the repo's local mcp/ package shadowed the pip MCP SDK (namespace
  collision; the loader now imports the real SDK subtree and restores the
  local package), SDK detection only recognized the legacy file layout, and
  FastMCP 1.x rejected legacy constructor kwargs. The launcher checks
  python3 and SDK importability, offers a consent-gated dependency
  bootstrap into the project-local .loki/mcp-venv (non-TTY/CI never
  install: honest manual command and exit 2; LOKI_NO_INSTALL_OFFER=1
  opt-out), and execs the server over stdio with the install root on
  PYTHONPATH while preserving the user's cwd for .loki resolution.
  Verified by a real MCP initialize/tools-list handshake from a non-repo
  directory: 34 tools. Known narrow residual (documented in code): a user
  cwd containing its own Python package literally named mcp still shadows
  under python -m.
• Bare loki landing now also points at loki web (the visual builder)
  alongside the run monitor.

Fixed

• CRITICAL (caught by the adversarial pre-release hunt, never shipped): the
  first loki mcp implementation launched the pip SDK's stub server with
  ZERO Loki tools whenever run outside the install root, because the SDK
  probe cd-ed into the install root while the launch did not. The
  PYTHONPATH-based fix above closes it, with a decoy-SDK regression test
  that fails on the old behavior.
• loki web stop no longer kills unrelated live loki runs: the machine-wide
  orchestrator pkill was removed (Purple Lab's own children are still
  reaped via its scoped child-pids ledger), with a foreign-survival
  regression test.
• Piped/redirected output of the bare-loki landing and loki demo no longer
  contains ANSI color codes (TTY-gated in addition to NO_COLOR).
• MCP tool count corrected to 34 across README, wiki, and walkthrough docs
  (verified by live handshake; one tool registered but gated on the managed
  memory/agents env vars), replacing stale "15 tools" claims.
• The bundled demo PRD gained an acceptance line requiring a basic automated
  check, still classifying SIMPLE (score 0, ~$1.86 estimate).
• docker-compose.yml's first-line comment is version-free (was stale since
  v6.73.1).

Tests

• New: tests/cli/test-mcp-launch.sh (8 cases incl. the non-repo-cwd
  decoy-SDK P0 regression), tests/test-web-stop-scoping.sh (5).
  tests/test-cli-commands.sh: 26/26 on both routes. tests/test-plan-command.sh:
  25/25. A real MCP stdio handshake check is wired into scripts/local-ci.sh.
