/**
 * OpenClaw lifecycle hooks for the Shroud privacy plugin.
 *
 * Privacy architecture — two directions, one fetch intercept:
 *   Outbound (obfuscation):  globalThis.fetch intercept replaces real PII
 *                            with deterministic fakes before ANY LLM API call.
 *   Inbound (deobfuscation): Same fetch intercept buffers the LLM's SSE
 *                            response per content block, deobfuscates fakes
 *                            back to real values, and returns clean events.
 *                            OpenClaw never sees fakes — all channels, sessions,
 *                            and delivery paths receive real text automatically.
 *
 * Hooks:
 * 1. before_prompt_build   (async) -- pre-seed mapping store for the fetch intercept
 * 2. before_message_write  (SYNC)  -- deobfuscate assistant messages for transcript
 * 3. before_tool_call      (async) -- deobfuscate tool params (+ depth tracking)
 * 4. tool_result_persist   (SYNC)  -- obfuscate tool result message
 * 5. message_sending       (async) -- deobfuscate outbound message content (backup)
 * 6. globalThis.__shroudStreamDeobfuscate -- streaming event deobfuscation hook
 * 7. globalThis.__shroudDeobfuscate       -- channel delivery deobfuscation hook
 * 8. globalThis.fetch intercept           -- obfuscates requests, deobfuscates responses
