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.

+# EverMem Projects
+View all Claude Code projects that have been tracked by EverMem.
+
+## Instructions
+
+Show the user their projects stored in the local groups.jsonl file.
+
+1. Read the groups file from the plugin's data directory
+2. Aggregate entries by groupId (count sessions, find first/last seen)
+3. Display the project table with statistics
+4. If no groups file exists, explain that projects are tracked automatically
+
+## Actions
+
+Check and read the groups data file:
+
+```bash
+GROUPS_FILE="${CLAUDE_PLUGIN_ROOT}/data/groups.jsonl"
+if [ -f "$GROUPS_FILE" ] && [ -s "$GROUPS_FILE" ]; then
+  cat "$GROUPS_FILE"
+else
+  echo "NO_GROUPS_FILE"
+fi
+```
+
+**Note:** The file uses JSONL format (one JSON object per line). Each line is a session start event.
+
+Entry format: `{"keyId":"...","groupId":"...","name":"...","path":"...","timestamp":"..."}`
+
+- `keyId`: SHA-256 hash (first 12 chars) of the API key - associates projects with accounts
+- `groupId`: Short identifier (9 chars: project name prefix + path hash)
+
+Aggregate by `keyId + groupId` when displaying:
+- Count occurrences = sessionCount
+- Earliest timestamp = firstSeen
+- Latest timestamp = lastSeen
+
+## Output Format
+
+If projects exist:
+```
+📁 Claude Code Projects
+
+| Project             | Group ID   | Sessions | Last Active |
+|---------------------|------------|----------|-------------|
+| evermem-claude-code | ever8d8d5  | 42       | just now    |
+| my-react-app        | myrea1b2c3 | 12       | 2h ago      |
+
+Total: 2 projects
+```
+
+If no projects file:
+```
+📁 Claude Code Projects
+
+No projects tracked yet. Projects are automatically recorded when you start Claude Code sessions.
+
+Each project directory creates a unique group ID for organizing memories.
+```
+
+## Notes
+
+- Projects are identified by working directory path (hashed to 9-char ID)
+- Each project has its own memory namespace in EverMem Cloud
+- The groups.jsonl file is appended by the SessionStart hook
+- Same project used with different API keys will appear as separate entries
+- `keyId` is a SHA-256 hash (first 12 chars) of the API key - secure and unique
