[amit-amazon]

Superseded by #20 (merged), a coordinated catch-up that bumps these minor/patch updates in one coherent re-lock so the runtime-requirements export gate passes. Verified: 226 unit tests + live graph/swarm eval on redeployed AgentCore (strands 1.48, agentcore 1.18.1, otel 1.44). Closing.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
