refactor: annotate module-level allocations with /* @__PURE__ */

C07 — allow bundlers to drop unused allocating consts. Four sites:
SELF_CLOSING_TAGS, UNSAFE_KEYS (new Set); useHotkey/parsing logger
(useLogger call); createValidation UNSET (Symbol call). Plain
object literals (BLACK, WHITE) exempt.
