fix(bridge): rawRPC direct polling + SDK analysis docs + trial-and-error log

- Root cause: getDiagnostics.lastStepIndex is stale, SDK EventMonitor cannot detect real-time step changes
- Fix: Direct rawRPC('GetCascadeTrajectorySteps') polling every 5s
- Relay: PLANNER_RESPONSE, NOTIFY_USER, TASK_BOUNDARY, WAITING steps
- Added: docs/discord-bridge-analysis.md (full SDK architecture analysis)
- Added: docs/devlog/entries/20260308-003.md (trial-and-error history)
- Added: antigravity-sdk-main/ source reference
- Vikunja: #252 done, #253 created, #251 commented

* Integrity Manager — Suppress Antigravity's "corrupt installation" warnings.
*
* When the SDK patches workbench files, Antigravity's IntegrityService detects
* checksum mismatches and shows two warnings:
* 1. Console WARN ("Installation has been modified on disk")
* 2. UI Notification ("Your Antigravity installation appears to be corrupt")
*
* This class updates ALL mismatched SHA256 hashes in product.json, so
* IntegrityService sees isPure=true and produces no warnings at all.
*
* Handles not just workbench.html but also workbench.desktop.main.js (auto-run fix),
* workbench-jetski-agent.html (agent manager patching), and any other modified files.
*
* Multi-extension coordination: a registry file (.ag-sdk-integrity.json)
* in the workbench directory tracks active SDK namespaces and the original
* hashes, so the last extension to uninstall restores the original state.
*
* @module integration/integrity-manager
