refactor: multi-provider memory adapters with scan-based builtin (#227)

* refactor: restructure memory into multi-provider adapters, remove manifest.json dependency

- Rename internal/memory/provider to internal/memory/adapters with per-provider subdirectories (builtin, mem0, openviking)
- Replace manifest.json-based delete/update with scan-based index from daily files
- Add mem0 and openviking provider adapters with HTTP client, chat hooks, MCP tools, and CRUD
- Wire provider lifecycle into registry (auto-instantiate on create, evict on update/delete)
- Split docker-compose into base stack + optional overlays (qdrant, browser, mem0, openviking)
- Update admin UI to support dynamic provider config schema rendering

* chore(lint): fix all golangci-lint issues for clean CI

* refactor(docker): replace compose overlay files with profiles

* feat(memory): add built-in memory multi modes

* fix(ci): golangci lint

* feat(memory): edit built-in memory sparse design
