* feat(bedrock-mantle): add IAM credential auth via @aws/bedrock-token-generator
Mantle previously required a manually-created API key (AWS_BEARER_TOKEN_BEDROCK).
This adds automatic bearer token generation from IAM credentials using the
official @aws/bedrock-token-generator package.
Auth priority:
1. Explicit AWS_BEARER_TOKEN_BEDROCK env var (manual API key from Console)
2. IAM credentials via getTokenProvider() → Bearer token (instance roles,
SSO profiles, access keys, EKS IRSA, ECS task roles)
Token is cached in memory (1hr TTL, generated with 2hr validity) and in
process.env.AWS_BEARER_TOKEN_BEDROCK for downstream sync reads.
Falls back gracefully when package is not installed or credentials are
unavailable — Mantle provider simply not registered.

* feat(bedrock): add Bedrock Mantle (OpenAI-compatible) provider
New amazon-bedrock-mantle extension that provides auto-discovery and
authentication for Amazon Bedrock Mantle endpoints.
Mantle (bedrock-mantle.<region>.api.aws) is Amazon Bedrock's OpenAI-
compatible API surface, separate from the existing bedrock-runtime
(ConverseStream) endpoint. It has its own model catalog including
models not available via ConverseStream (e.g. openai.gpt-oss-120b,
mistral.devstral-2-123b).
Extension structure:
- discovery.ts: Model discovery via GET /v1/models (OpenAI format),
bearer token resolution, implicit provider configuration
- register.sync.runtime.ts: Provider registration with catalog,
error classification (rate limits, context overflow)
- openclaw.plugin.json: Plugin manifest, enabledByDefault
Auth support:
- Long-lived Bedrock API key (AWS_BEARER_TOKEN_BEDROCK env var)
created from the AWS Console → used directly as Bearer token
- Pre-generated SigV4-derived tokens (via aws-bedrock-token-generator)
set in AWS_BEARER_TOKEN_BEDROCK → works transparently
Provider config (auto-resolved when AWS_BEARER_TOKEN_BEDROCK is set):
api: "openai-completions"
baseUrl: "https://bedrock-mantle.<region>.api.aws/v1"
auth: "api-key" (bearer token)
Available in 12 regions: us-east-1, us-east-2, us-west-2,
ap-northeast-1, ap-south-1, ap-southeast-3, eu-central-1,
eu-west-1, eu-west-2, eu-south-1, eu-north-1, sa-east-1
Tests: 15 passing (13 discovery + 2 plugin registration)
