Summary

AI summary

Notification tokens migrated from plain‑text config to OS keychain storage.

Full changelog

Fixed

doctor --fix apt hang — DEBIAN_FRONTEND=noninteractive prefix added to apt fix commands over SSH
restore --force bypass — --force flag now auto-selects the latest backup without prompting
README codecov badge — Replaced broken codecov.io badge URL with shields.io integration

Security

Notify token keychain migration — Notification tokens moved from plain-text config to OS keychain storage with secure file-backed fallback
SSH command builder — New SshCommand branded type with cmd()/raw() builders and POSIX shellEscape() — eliminates string concatenation injection risk across 11 core modules

Changed

MCP SDK isolation — Dynamic import() boundary ensures non-MCP commands never load MCP SDK's 179 transitive dependencies
execSync → spawnSync migration — Shell invocation eliminated from ssh.ts and doctor.ts
MCP handler decomposition — serverSecure (10 handlers) and serverBackup (6 handlers) extracted with 63 new unit tests
Quality audit fixes — 16 code quality findings resolved
Test count: 3,175 → 3,333 (+158 new tests)
