Warp: tab color cycling, agent platform icons, Oz renamed to Warp Agent, and dozens of fixes

Improvements

• Tab color cycling: customizable action from keybinding or Command Palette
• Cloud agent run details: show macOS/Linux platform icon alongside architecture and runner
• Command completions: vagrant (nested command groups plus dynamic machine/box names), openssl, Yandex Cloud CLI (yc), git worktree names, journalctl (units, boots, fields, syslog identifiers)
• Tab autocomplete: follows symlinks to directories in remote/SSH sessions

Bug fixes
