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.

+"""Dump the FastAPI OpenAPI schema to ``docs/openapi.json``.
+
+Static export — does **not** start the server. Calls ``app.openapi()``
+directly on the FastAPI instance returned by ``create_app()``, which
+the runtime ``GET /openapi.json`` handler returns verbatim. No lifespan
+is run, so this is fast and side-effect-free.
+
+Modes:
+
+* default — write ``docs/openapi.json``.
+* ``--check`` — write to a temp file and ``diff`` against the on-disk
+  copy. Exits non-zero on drift, so it can be wired into ``make lint``
+  to fail PRs that touch the API surface without regenerating the
+  committed schema. Same shape as ``check_datetime_discipline.py``.
+
+Run::
+
+    python scripts/dump_openapi.py            # write docs/openapi.json
+    python scripts/dump_openapi.py --check    # CI gate
