Merge step (d): content merges for README and ce-brainstorm/plan/work

Applies triage docs 016-019 — merges upstream's structural refactor with
local's fork-specific additions.

README:
- Drop entries for locally-removed agents (dhh/kieran-rails, design/*,
  ankane-readme-writer, performance-oracle, security-sentinel,
  data-migration-expert)
- Add local custom skills (ce-john-voice, ce-hugo-blog-publisher,
  ce-story-lens, ce-essay-outline, ce-essay-edit, ce-excalidraw-png-export,
  ce-sync-confluence, ce-jira-ticket-writer, ce-upstream-merge,
  ce-proof-push, ce-ship-it, ce-weekly-shipped) under appropriate sections
- Add local custom agents (ce-design-conformance-reviewer,
  ce-tiangolo-fastapi-reviewer, ce-zip-agent-validator, ce-lint,
  ce-python-package-readme-writer)
- Add ce-fastapi-style, ce-python-package-writer to Development Frameworks
- Preserve "privacy/compliance angle" suffix on ce-data-integrity-guardian
- Add ce-previous-comments-reviewer entry (present in code, was missing
  from README)
- Update component counts to match actual filesystem (47 agents, 50 skills)

ce-brainstorm: insert Deploy wiring flag paragraph once in Phase 2
approach presentation (local carried this edit; deduped the accidental
double-insertion from the local diff).

ce-plan: insert Deploy wiring check bullet in "Every plan should contain"
list and in Phase 1 Repo Scan Signals section.

ce-work: insert "Did I add new env vars or config fields?" row in the
Phase 2 pattern-sensitive check table.

ce-work shipping-workflow: insert "If new env vars added to backend
config, deploy values files updated in same PR" line in pre-PR checklist.

All deploy-wiring additions reference
docs/solutions/deployment-issues/missing-env-vars-in-values-yaml.md
(note: the referenced solution doc doesn't exist yet — flagged for
follow-up).
