Replace "client agents" with "agent clients" and "database agents" with
"data agents" across AGENTS.md, README.md, the docs-site copy, and the
matching setup-agents test description, matching the canonical
vocabulary in docs/terminology.md.
Also moves packages/cli/tsconfig.json's tsBuildInfoFile from
node_modules/.cache/ to dist/.tsbuildinfo so incremental builds survive
node_modules reinstalls.
Drop the duplicate `pnpm run build` (artifacts:build already builds every
package). Run package builds in parallel topology via one recursive pnpm
invocation. Enable incremental tsc and keep the cli's tsbuildinfo outside
its dist (moved the dist wipe into a separate `clean` script). Run the
final `ktx status` doctor from a temp dir so it stops walking up into a
parent ktx.yaml and failing the script.
Conductor setup drops from ~26s to ~9.8s cold and ~4.4s warm.
