- providers.ts: drop the `dup` intermediate, fold the ternary inline
- paths.ts (fmtCwdBranch): inline `b` into the `tag` template
- prompts.tsx (ConfirmPrompt): hoist a single `lower = ch.toLowerCase()`,
collapse the three early-return branches into two, drop the
redundant bounds checks on arrow-key handlers (setSel is idempotent
at 0/1), inline the `confirmLabel`/`cancelLabel` defaults at the
use site
- modelPicker.tsx / config/env.ts / providers.test.ts: auto-formatter
reflows picked up by `npm run fix`
- useInputHandlers.ts: drop the stray blank line that was tripping
perfectionist/sort-imports (pre-existing lint error)
If the gateway returns two providers that resolve to the same display name
(e.g. `kimi-coding` and `kimi-coding-cn` both → "Kimi For Coding"), the
picker now appends the slug so users can tell them apart, in both the
provider list and the selected-provider header. No-op when names are
already unique.
Refs #10526 — the Python backend dedupe from #10599 skips one alias, but
user-defined providers, canonical overlays, and future regressions can
still surface as indistinguishable rows in the picker. This is a
client-side safety net on top of that.
