chore(parity): refute G06 (false positive) + reconcile G08 merged (#32)

G06 re-verification: the audit claimed <Transform>'s fn gets a hardcoded
index 0 "instead of the childNode index". Ink's index (output.ts:230-239)
is the LINE index, applied per output line — not a child index; the audit
misread it. vue-tui already produces correct per-line line indices for
multi-line transforms (existing tests "transform with multiple lines" and
transform-yoga pass unmodified). paint.ts:314's transform(innerText, 0) is
only the inline <Transform>-in-<Text> path (single logical line, 0 matches
Ink). No observable gap — marked refuted, not fixed.

Also reconciles G08 -> merged (landed in #31).

   - _"Box background with border fills content area"_: inline snapshot updated — border rows (`╭───╮`/`╰───╯`) no longer carry bg; inner rows keep it.
   - _"Box backgroundColor survives border rendering"_: unchanged, still passes (the inner fill keeps the bg).
   - Added _"Box backgroundColor does not bleed onto border glyphs (Ink parity)"_ as the failing-first reproduction.
+- **2026-05-29 — G06 REFUTED (false positive from the audit):** the audit claimed `<Transform>`'s fn gets a hardcoded index `0` "instead of the childNode index". Re-verification against Ink `output.ts:230-239` shows Ink's index is the **line index** (transformers apply per output line: `transformer(line, index)`), not a child index — the audit misread it. vue-tui **already** applies per-line line indices for multi-line (block) transforms via the yoga-carrier path: the existing tests `transform with multiple lines` → `[0: hello world]\n[1: goodbye world]` and transform-yoga `[0: hello]\n[1: world]` pass on unmodified code. `paint.ts:314`'s `transform(innerText, 0)` is only the inline `<Transform>`-inside-`<Text>` path, whose content is a single logical line where `0` matches Ink (all inline tests assert `[0: …]`). No observable gap; not fixed.
