docs: replace runtime dlp-profiles refs with runtime dlp profiles

[cdot65]

Summary

Companion docs PR to #227 (which removed the legacy airs runtime dlp-profiles list command). Replaces lingering runtime dlp-profiles references in manually-authored docs with the canonical airs runtime dlp profiles list.

• docs/runtime/config-management.md — DLP Profiles snippet updated to new command
• docs/architecture/overview.md — Runtime Security row updated (runtime dlp-profiles → runtime dlp umbrella)
• docs/development/full-cli-sweep.md — section B.1 example + B.4 distinguishing parenthetical (no longer relevant)
• docs/cli/examples/runtime.yaml — deleted the legacy "runtime dlp-profiles list": stanza (the canonical "runtime dlp profiles list": key already exists earlier in the file)

Auto-generated CLI reference pages under docs/cli/** were already refreshed by #227 (pnpm docs:gen). The release-notes Migration note for the removal also already ships in #227 — verified, not duplicated here.

Historical references in docs/about/release-notes.md (older release entries) and docs/superpowers/{plans,specs}/... left intact as historical record per the handoff scope.

Test plan

• pnpm docs:check — OK (123 commands, 30 on allowlist)
• pnpm docs:build — mkdocs --strict green (2.15s)
• grep -rn "dlp-profiles" docs/ — remaining hits are unrelated --dlp-profiles security-profile flag references in auto-gen pages, or historical release-note entries (intentionally untouched)
• Reviewer: skim the four touched pages in the rendered site
