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

-1. Use `lh memory list` to inspect shards.
-2. Use `lh memory get --shard <name>` to read one shard.
-3. Use `lh memory put --shard <name>` to write durable facts.
-4. Use `lh memory scan` before risky writes.
-5. Use `lh memory compact` when shards grow noisy.
+1. Invoke `.github/agents/conductor.agent.md` and ask for the `memory` operation.
+2. Conductor runs only the `memory` row of its OPERATIONS table and reports the result.
 
-Never write secrets to memory.
+Do not duplicate conductor's steps here -- see `conductor.agent.md` section OPERATIONS for the authoritative procedure.
