v2.9.0

• Redesigned host list with smarter column layout and provider tag separation
• Provider tags are now stored in a dedicated comment and always mirror the remote. Your own tags are never touched by sync
• Two-cluster column system. Left cluster (name and host) and right cluster (auth, tags, last) separated by a flexible gap
• Add header underline and bold column headers for better scannability
• Add sort indicator next to the active sort column name
• Add selection indicator on the left edge of the selected row
• Show dash for empty auth and last cells instead of blank space
• Show read-only provider tags in the tag edit bar
• Group headers show a horizontal leader line after the label
• Tighter column gaps (2-3 fixed) for a more compact and professional look
• Shorten time labels in the last column (5m instead of 5m ago)
• Sanitize tag values: strip control characters, commas, bidi overrides and enforce max length
• Remove --reset-tags CLI flag (no longer needed)
