v0.3.0

Agent Session Pack v0.3.0

New providers

• Grok — multi-file session directories under ~/.grok/sessions (skips active sessions)
• Kimi Code — multi-file sessions under ~/.kimi-code/sessions
• OpenCode — local stores under ~/.local/share/opencode / ~/.opencode
• Gemini CLI — local stores under ~/.gemini

Core

• Directory-backed sessions pack/restore as verified tar.zst trees
• Tree content hashing for byte-exact multi-file restore
• Manifests record sourceKind: file | directory

Verification

• Unit/integration suite green
• E2E on one cold Grok session: pack → remove original → unpack → identical tree hash (60KB → ~21KB, ~64% savings)
• Live check --provider grok on this machine: 493 sessions found, byteExact true, originals untouched

Cursor and Devin remain backup-only.
