秦奇 c7aa4a4019 feat(cli): add ui.customBannerSubtitle for the spacer row
Adds a fourth opt-in setting to the banner customization surface.
The info panel renders four rows (title, subtitle/spacer, status,
path); the second row was a hard-coded single-space spacer up to
now. With this change a fork or white-label deployment can set
`ui.customBannerSubtitle` to a one-line subtitle (e.g. "Built-in
DataWorks Official Skills") and have it render in the secondary
text color in place of the spacer. Empty/unset preserves the
previous blank-spacer layout, so the change is back-compat.

The subtitle is sanitized through the same
`sanitizeSingleLine` helper as the title (now factored out): OSC /
CSI / SS2 / SS3 leaders dropped, every other C0/C1 control byte
replaced with a space, internal whitespace collapsed, ends
trimmed. Capped at 160 characters — looser than the title's 80
because tagline / "powered by" copy commonly runs longer — with
the same `[BANNER]` warn on truncation.

Wiring:

- `settingsSchema.ts` — new `customBannerSubtitle` entry next to
  `customBannerTitle`, `showInDialog: false` (free-form text in
  the TUI dialog isn't worth its own picker).
- `customBanner.ts` — `ResolvedBanner.subtitle` field;
  `resolveCustomBanner` populates it; `sanitizeTitle` and the new
  `sanitizeSubtitle` share the same helper.
- `Header.tsx` — when `customBannerSubtitle` is truthy the spacer
  row renders the string (secondary color, single line) instead
  of `<Text> </Text>`. Auth/model and path still sit at their
  usual positions.
- `AppHeader.tsx` — pipes `resolvedBanner.subtitle` through.
- VSCode JSON schema regenerated from source (idempotent).

Tests: 5 new resolver tests (default, sanitize, length cap,
empty, newline + C1 strip), 2 new Header tests (renders subtitle
between title and auth; spacer preserved when unset), 1 new
AppHeader integration test (end-to-end through resolver). Banner
suite is now 35 + 17 + 6 + 16 = 74 tests, all green.

Design docs (EN + zh-CN) updated: region taxonomy now lists four
B-rows; "Limits at a glance" table grows a subtitle row;
"Customization rules" matrix and "How to modify" section gain a
"Add a brand subtitle" example with a rendered four-row preview.
