ci: add release workflow for proxy package

[guytepper]

Allow publishing @decartai/proxy to npm independently from the SDK.

Changes:

• Update release.yml to support separate tag patterns: sdk-v* and proxy-v*
• Added dynamic package detection based on git tag
• Added bumpp and release script to the proxy package
• Updated SDK's release script to use sdk-v%s tag format

Usage:

• To release SDK: cd packages/sdk && pnpm release
• To release Proxy: cd packages/proxy && pnpm release
