v3.5.0

• feat: Vault SSH connects through bastions on the first try.
• feat: Active tab stays crisply underlined on every terminal, including macOS Terminal where the highlight used to bleed across tabs.
• feat: The selected host's ping dot self-refreshes as you arrow through the list, so freshness follows your cursor.
• feat: When Vault signing fails, the toast tells you the actual cause instead of being shadowed by the generic SSH error.
• change: Proxmox sync breaks down partial failures by category (timeout, HTTP 5xx, HTTP 4xx, transport, parse) in the summary line.
• change: Pre-commit gates catch hardcoded user-facing text and convention drift before they ship, so error wording stays consistent.
• change: Smoke tests verify each screen actually renders, not just that the binary stays alive.
