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.

+CairoSVG is dynamically linked through ``everalgo-parser`` and is only
+pulled in when the user explicitly opts into the ``multimodal`` extra.
+LGPL-3.0 is compatible with Apache-2.0 redistribution in this dynamic-
+linking arrangement; if you statically link or modify CairoSVG itself,
+the LGPL-3.0 terms apply to that derivative work.
