chore: initialize EverOS 1.0.0

md-first memory extraction framework for AI agents.

Markdown is the single source of truth; SQLite holds state and LanceDB
provides the rebuildable vector + BM25 + scalar index. The codebase follows
a single-direction DDD layering (entrypoints -> service -> memory -> infra,
with component / core / config cross-cutting) enforced by import-linter.

Engineering surface:
- Coding conventions in .claude/rules/ (path-scoped) and workflows in
  .claude/skills/ (/commit, /new-branch, /pr).
- GitHub Actions CI runs make lint + test + integration; pre-commit mirrors
  the gates locally (ruff, hygiene hooks, gitlint commit-msg).
- Commit messages follow Conventional Commits, enforced by gitlint.
- make lint also enforces datetime two-zone discipline and OpenAPI drift.

+
+Thanks to the following projects, communities, and individuals for their
+inspiration and support.
+

+
+## Inspiration & references
+
+### [memsearch](https://github.com/zilliztech/memsearch)
+
+Inspired our markdown-as-source-of-truth design and the SHA-256 +
+file-watcher incremental sync model. memsearch is the closest project in
+spirit to EverOS.
+
+### [mem0](https://github.com/mem0ai/mem0)
+
+Inspired the "one provider per file" flat adapter layout that EverOS uses
+for `component/llm/` and `component/embedding/`.
+
+### [Letta (MemGPT)](https://github.com/letta-ai/letta)
+
+Inspired the multi-tier memory mapping (Core / Recall / Archival) that maps
+naturally onto our MemCell / Episode / Archival pipeline.
+
+### [MemOS](https://github.com/MemTensor/MemOS)
+
+Provided a reference for memory taxonomy decisions (textual / parametric /
+activation) and helped sharpen our scope choice to focus on textual memory.
+
+### [Memos](https://github.com/usememos/memos)
+
+A comprehensive open-source note-taking service whose plain-text-first
+design philosophy reinforced our decision to keep markdown files as the
+single source of truth.
+
+### [Nemori](https://github.com/nemori-ai/nemori)
+
+A self-organising long-term memory substrate for agentic LLM workflows that
+provided valuable inspiration for our extraction pipeline.
+

+
+## Open-source libraries
+
+EverOS is built on top of excellent open-source libraries and frameworks:
+
+### Core
+
+- **[Python](https://www.python.org/)** — Programming language (3.12+)
+- **[uv](https://github.com/astral-sh/uv)** — Fast Python package manager
+- **[FastAPI](https://fastapi.tiangolo.com/)** — Modern async web framework (HTTP API)
+- **[Pydantic](https://docs.pydantic.dev/)** — Data validation and settings
+
+### Storage
+
+- **[LanceDB](https://lancedb.com/)** — Embedded vector + BM25 + scalar database
+- **[SQLite](https://sqlite.org/)** — Embedded relational database (state + audit log)
+
+### Tooling
+
+- **[Ruff](https://docs.astral.sh/ruff/)** — Lint + format
+- **[import-linter](https://import-linter.readthedocs.io/)** — Layered architecture enforcement
+- **[Hatchling](https://hatch.pypa.io/)** — Wheel build backend
+- **[pytest](https://pytest.org/)** — Testing framework
+- **[pre-commit](https://pre-commit.com/)** — Git hooks framework
+
+### LLM & embedding providers
+
+EverOS is provider-agnostic by design. Tested provider integrations include
+OpenAI, Anthropic, Ollama, and SBERT. See [`component/llm/`](src/everos/component/llm/)
+and [`component/embedding/`](src/everos/component/embedding/) for the
+adapter layouts.
