v0.6.28

Highlights

• This release covers every PR merged after 0.6.27, including workflow approval gates, coding-agent fixes, scheduled-job model selection, completed session exports, Web UI 0.6.28 metadata, and MCU firmware recovery updates.
• MCU Wi-Fi startup and reconnect now scan saved network history before connecting, with reprovisioning available without clearing history and a separate clear-history action.
• ESP32-C3 firmware now supports remote active-machine reauthentication so target machine reconnects can refresh MCU login without clearing the active device.
• MCU speech playback segmentation now follows completed paragraphs instead of a fixed 90-character soft boundary.
• Desktop version metadata and public version listings now include Web UI 0.6.28, with localized sidebar update copy.
• Coding-agent workspace diffs and session exports received fixes for new files, SQLite sidecars, completed sessions, abort routing, and scoped MCP inheritance.
