(DOCS) Update changelog for 3.2.* releases

[michaeltlombardi]

PR Summary

This change adds entries to the changelog for the 3.2.0, 3.2.1, and 3.2.2 releases, including new features, bug fixes, and improvements.

It provides a comprehensive overview of the changes made in these releases, helping users understand the updates and enhancements. Each entry links to related work items.

This change adds the entries but doesn't provide links to the reference or conceptual documentation. Those links will be added in the future after review and drafting of the required documentation updates.

PR Context

Need to update the changelog for the latest releases. This also serves as a sync for reference and conceptual content that needs updating.

For this PR we need technical review - the changelog will iteratively update during the rest of the documentation process but reflects my current understanding of the changes to DSC.

CHANGELOG.md:162

• The MCP tool list for dsc mcp doesn’t match the tool names exposed by the server in this repo (e.g., list_dsc_resource / list_adapted_resources don’t exist; the server exposes list_dsc_resources, list_dsc_functions, show_dsc_schema, etc.). Also, the protocol name is typically written as JSON-RPC (hyphenated). Updating this list avoids publishing incorrect tool names in the 3.2.0 changelog entry.

- Added the `dsc mcp` command to start DSC in server mode. In this mode, DSC acts as a JSON RPC
  server. For this release, the server primarily enables use as a Model Context Protocol (MCP)
  provider. The server supports the following functions (tools in MCP):

  - `list_resources`

CHANGELOG.md:1742

• The issue/PR reference link list appears to be kept in numeric order, but the newly added [#50] and [#57] entries are currently out-of-order, which makes the reference section harder to scan/maintain. Consider reordering these entries numerically with the surrounding links.
