Prune stale docs and update .hermes content

Delete a large set of outdated documentation (many files under docs/ and .hermes/plans/, including audits, design, prd, technical, planning, assets, and todos). Update and consolidate .hermes content: refresh shared-memory pages (decision-log, development-workflow, document-map, pitfalls, project-overview, team-conventions) and several skills/references under .hermes/skills. Also modify AGENTS.md, README.md, UI_CODING_STANDARD.md, docs/README.md and .encoding-check-ignore. Purpose: clean up stale planning/audit material and keep current hermes documentation and related top-level docs in sync.
