docs(changelog): cut 1.7.0

[danielmeppiel]

Why

Cuts the v1.7.0 release covering the v0.12.3 fallout fixes:

• fix(isolated): inject target input into generated apm.yml #33 — propagate target: into the generated apm.yml (isolated mode), pin apm-version default to 0.12.3, drop the obsolete vscode alias from the documented allowlist.
• fix: validate target input before YAML/CLI interpolation #34 — strict allowlist validation on the target input (YAML / CLI injection guard).

CHANGELOG entry follows the existing Keep-a-Changelog format and includes a brief "Why these changes" rationale matching prior releases.

How to release

After merge, tag and push from main:

git checkout main && git pull
git tag -a v1.7.0 -m "Release v1.7.0"
git push origin v1.7.0

The release workflow in ci.yml will:

1. Force-update the v1 floating tag to the new commit.
2. Create a GitHub Release from the tag with auto-generated notes.

No package.json bump needed — the action is tag-versioned, not npm-versioned.

• Link reference definitions for PRs are otherwise grouped at the end of the file (e.g., [#2] … [#31]). Consider moving [#33] / [#34] down into that existing reference list to keep the changelog structure consistent and avoid scattering link definitions through the document.
