Mesa Description

TL;DR

This is an automated release PR for version 0.9.0, primarily introducing a new internal shimjson package to enable more granular control over JSON HTML escaping throughout the SDK.

Why we made these changes

To support the explicit feature of "optional JSON HTML escaping" as stated in the changelog, allowing for finer control over JSON serialization and enabling specific API requirements or data representations by selectively enabling/disabling HTML escaping.

What changed?

• .release-please-manifest.json: Updated for the v0.9.0 release tracking.
• .stats.yml: Updated project statistics configuration.
• CHANGELOG.md: Added a new 0.9.0 version entry, highlighting the support for optional JSON HTML escaping.
• README.md: Updated the go get command example to reference version v0.9.0.
• internal/encoding/json/encode.go: Modified the Marshal function to make default HTML escaping conditional, controlled by the shims.EscapeHTMLByDefault flag.
• internal/encoding/json/shims/shims.go: Introduced a new boolean constant EscapeHTMLByDefault set to true to control the default HTML escaping behavior.
• internal/requestconfig/requestconfig.go: Changed JSON serialization for the request body from json.Marshal to json.NewEncoder().SetEscapeHTML(true), explicitly enforcing HTML escaping for outgoing request bodies.
• internal/version.go: Updated the SDK's internal version number to v0.9.0.
• packages/param/option.go: Replaced standard json.Marshal with shimjson.Marshal in Opt[T] type's MarshalJSON methods for consistent JSON marshalling.
• shared/constant/constants.go: Switched from the standard encoding/json package to shimjson for all JSON marshalling operations within constants.
