A nested <Text> inside a styled <Text> now inherits the ancestor's bold/italic/
underline/strikethrough/dim -- previously those closed at the nested boundary.
Rewrites inline-text composition from merge-down + per-leaf applyChalk to Ink's
wrap-the-concatenation model (squash-text-nodes.ts + render-node-to-output.ts:136):
each Text's own style wraps the concatenation of its already-styled children, so
<Text bold>A<Text green>B</Text></Text> = chalk.bold("A" + chalk.green("B")) --
bold stays open across the green child.
A bare text-leaf now contributes its RAW value (Ink's #text carries no transform);
all styling incl. the effective bg (ownBg ?? inheritedBg) is applied once by the
enclosing Text's wrap. This also makes the nested-inline backgroundColor="" case
match Ink, and is more Ink-faithful for bare text under a <Transform> (no Box bg on
its glyphs -- Ink's Transform doesn't consume backgroundContext), locked by a test.
G52 comment-anchor index handling preserved. Adds 11 exact-byte tests.
