chore(oss): sync the SDK mirrors to 2.1.1

Python 2.1.1 is published to PyPI and Go v2.1.1 to the module proxy; npm
still serves 2.0.1 until the Node publish.

 - Console registration wizard synced with the hosted Console: native hook catalog with activation steps, a one-command install that embeds both credentials in owner-only files (created exclusively with `mktemp` on POSIX; created under `$HOME` and protected with `chmod 600` or an `icacls` owner-only ACL in PowerShell) and deletes them afterwards, and a never-expiring default API token.
 - Server issues opaque API tokens: `POST /v1/auth/token` honours `ttl_seconds` (`null` never expires), stores only SHA-256 hashes (migration 003), and resolves bearer values as API tokens before Better Auth sessions.
 - Server commits operations before enqueueing; a `seq_no` race now returns `400 PREV_HASH_MISMATCH` with the stored chain hash, and every queue producer names its durable message id.
-- SDK mirrors rebuilt from the standalone repositories at Node 2.1.0, Python 2.1.0, and Go v2.1.0 plus the unreleased fixes listed below; npm serves 2.0.1 and PyPI serves 2.0.2 until the next publish. The mirrors live under `github.com/Elydora-Infrastructure/Elydora-Go-SDK/v2` (hook retry on `PREV_HASH_MISMATCH` within a 4-second budget, durable managed-file transactions, Kiro IDE adapter, shared managed-runtime modules).

 - Compose and Helm apply `packages/server/migrations` through one runner (`node dist/migrate.js`); migrations already recorded in `schema_versions` are skipped. Migration 004 restores the status constraints, the agent organization foreign key, and the 64-bit counters that the previous inline Compose schema carried.
 - Server emits `AGENT_REVOKED` and `KEY_RETIRED` instead of reusing `AGENT_FROZEN` and `KEY_REVOKED`, matching the hosted API and the protocol specification.
