Bumps the Agent 365 CLI (Microsoft.Agents.A365.DevTools.Cli) to 2.0, released alongside SDK 2.0.0. The [Unreleased] changes include several breaking changes (removed commands, removed --config, and renamed flags), so this is a major version bump.

Changes

• src/version.json: version 1.1 -> 2.0. The scheme is unchanged; the patch number is still the git height.
• CHANGELOG.md: the current [Unreleased] content is now ## [2.0.0] - 2026-10-20, with a new empty ## [Unreleased] above it. The compare links at the bottom are updated to match.

No other files reference the CLI's 1.1 version. Matches in VersionCheckHelper/tests, manifest.json, and ToolingManifest are unrelated version strings.

Version verification

The heading says 2.0.0, but the published package will be 2.0.<height>. NB.GV resets the height when version.json changes. I simulated the squash merge onto origin/main (260fcca) and ran a public build on refs/heads/main with nbgv get-version (3.10.94):

Version:             2.0.1.12382
NuGetPackageVersion: 2.0.1

So the merge commit should produce 2.0.1. If another commit lands on main first, the result is still 2.0.1, because the height counts from the commit that changes version.json.
