/**
 * Generates a deterministic `_Toc`-prefixed bookmark name from a block ID.
 *
 * Uses percent-style encoding to produce a valid OOXML bookmark name that is
 * **injective** — no two distinct block IDs can produce the same output.
 *
 * Encoding rules (using `_` as escape character):
 * - Alphanumeric chars except `_` pass through unchanged
 * - `_` is escaped as `__` (escape-the-escape)
 * - Any other character is escaped as `_xx` (two-digit lowercase hex)
 *
 * Examples:
 * - `ba2b746a-930a-...` → `_Tocba2b746a_2d930a_2d...`
 * - `p-1` → `_Tocp_2d1`
 * - `p1`  → `_Tocp1`   (no collision with `p-1`)
