Miguel Ángel c0ffdc0fb0 fix(core,studio): escape user values in querySelector attribute selectors
Extract cssAttrSelector to packages/core/src/utils/cssSelector.ts and
use it (or CSS.escape for browser-side code) at all 12 sites that
previously interpolated raw user-authored values into querySelector
attribute selectors. A " in a composition ID, script src, or
data-start value would produce a malformed selector that throws.

Node-side (core compiler/parser): uses the shared cssAttrSelector.
Browser-side (runtime, studio): uses native CSS.escape().

Supersedes #1568 which fixed only the 3 bundler sites.
