fix: suppress goconst for inline strings in CLI/TUI/data/platform

Newer golangci-lint versions flag intentionally inline strings (CLI
flags, shell names, SQL fragments, UI labels, hex colors) as goconst
candidates. These are deliberate design choices where extracting
constants would hurt readability.
