v0.11.0 — data layer + data flywheel

Minor release. Adds two local-first data capabilities: a cross-harness
monitoring/data layer and an approved-run data flywheel. Both stay private by
default, write regenerated runtime artifacts under ignored .agent/
subdirectories, and avoid remote telemetry or model training.

Added

• data-layer seed skill — local cross-harness monitoring. Adds
  .agent/skills/data-layer/SKILL.md and
  .agent/tools/data_layer_export.py to export dashboard-ready local data
  across Claude Code, Hermes, OpenClaw, Codex, Cursor, OpenCode, and custom
  loops sharing the same .agent/ brain. Outputs include agent events, cron
  timelines, KPI summaries, token/cost estimates, category breakdowns,
  dashboard.html, and daily-report.md. Runtime exports live under
  .agent/data-layer/, which is gitignored. Thanks to @danielfoch for PR #25.
• data-flywheel seed skill — approved runs to reusable artifacts. Adds
  .agent/skills/data-flywheel/SKILL.md and
  .agent/tools/data_flywheel_export.py to turn human-approved, redacted runs
  into trace records, context cards, eval cases, training-ready JSONL, and
  flywheel metrics. Runtime exports live under .agent/flywheel/, which is
  gitignored. The tool is local-only, model-agnostic, and does not train
  models or call external APIs. Thanks to @danielfoch for PR #26.
• Schemas, sanitized examples, tests, README sections, and architecture docs
  for both local data features.

Changed

• Seed skill count is now eight: skillforge, memory-manager, git-proxy,
  debug-investigator, deploy-checklist, design-md, data-layer, and
  data-flywheel.
• docs/architecture.md now describes five local modules: memory, skills,
  protocols, data layer, and data flywheel.

Migration

brew upgrade agentic-stack is enough. There are no on-disk schema changes.
The new runtime directories, .agent/data-layer/ and .agent/flywheel/, are
private and regenerated; both are gitignored.

Release

• Tag v0.11.0 cut from master.
• GitHub release: https://github.com/codejunkie99/agentic-stack/releases/tag/v0.11.0
• Formula/agentic-stack.rb bumped to v0.11.0 in a follow-up commit after
  the tag tarball existed and its sha256 could be computed.
