feat(conductor): consolidate all operations behind single entry point

- add OPERATIONS table to conductor.agent.md (init, doctor, onboard,
  index, memory, telemetry, design, plan, build, verify, integrate,
  fast-track) so the conductor agent runs any named operation directly
  instead of only the full pipeline
- thin every skill file to a one-line pointer into conductor's
  OPERATIONS table, removing duplicated procedure text (contributor
  rule: no duplicated behavior in prompts/skills)
- document the operations table in README.md and AGENTS.md
