chore(release): v1.2.1

[umair-ably]

Prepares the v1.2.1 release.

What's in this release

The only user-facing change since v1.2.0 is #419. The other 7 commits on main are internal CI hardening and are not changelog-worthy.

Fixed

• npx @ably/cli <command> now runs without a redundant ably token, so npx @ably/cli init works as expected. The package previously shipped two binaries, which stopped npx auto-selecting one; it now ships a single ably binary.

Changed

• The standalone ably-interactive global binary is no longer installed as a separate command. Interactive mode handles Ctrl+C in-process. The terminal server consumes this through a companion Dockerfile change (already merged).

This PR

• Bumps package.json 1.2.0 → 1.2.1
• Adds the 1.2.1 CHANGELOG entry

(packages/react-web-cli is versioned independently and unaffected, so it is not bumped — consistent with the v1.2.0 release.)

Validation

• pnpm prepare — build + manifest OK
• pnpm exec eslint . — 0 errors
• pnpm test:unit — 2534 passed, 1 skipped, 1 todo

After merge

Tag the merge commit on main to trigger the npm publish workflow:

git tag -a v1.2.1 -m "Release v1.2.1"
git push origin v1.2.1

Walkthrough

This PR prepares the v1.2.1 patch release. It bumps the package version from 1.2.0 to 1.2.1 and adds the corresponding CHANGELOG entry. The underlying fixes (single binary for npx compatibility, removal of the separate ably-interactive global binary) landed in earlier PRs — this PR just cuts the release.

Changes

Area	Files	Summary
Config	package.json	Version bumped 1.2.0 → 1.2.1
Docs	CHANGELOG.md	New [1.2.1] - 2026-06-30 entry documenting the npx fix and ably-interactive binary removal

Review Notes

• No code changes — this is a pure release housekeeping PR (version bump + changelog). There is nothing functionally new to test here.
• The two changelog items (npx single-binary fix, ably-interactive removal) reference #419 which is already merged; reviewers may want to confirm the changelog wording accurately reflects that PR's behaviour.
• After merge, a manual tag push (git tag -a v1.2.1 … && git push origin v1.2.1) is required to trigger the npm publish workflow — this is noted in the PR description and is a deployment consideration.
• packages/react-web-cli is intentionally not bumped (independently versioned), consistent with v1.2.0 release practice.

Clean release PR. The two changes are exactly right:

• CHANGELOG.md: v1.2.1 entry accurately describes the user-facing changes from PR #419 (single ably binary, removal of standalone ably-interactive binary). The date matches today (2026-06-30).
• package.json: Version bumped 1.2.0 → 1.2.1, consistent with the semver patch designation (bug fix only).

No source code changes, no logic to review. Good to merge.
