docs(changelog): the product noun is now "agent"

[indykish]

Adds a Jun 03, 2026 changelog entry for the user-facing terminology rename in usezombie: the thing you install is now consistently an agent (defined at first touch), instead of "zombie"/"the agent"/"a runtime" used interchangeably.

Brand (usezombie), CLI (zombiectl), routes, and API fields are unchanged — only user-visible wording. Historical entries untouched.

Greptile Summary

This PR adds a Jun 03, 2026 changelog entry documenting the user-facing terminology consolidation: the installable runtime is now consistently called an agent across the dashboard, marketing site, and docs. Brand names, CLI tokens, routes, and API fields are explicitly noted as unchanged.

• Introduces a new <Update> block with the standard ## What's new section structure and two bullet points covering dashboard UI surfaces and first-touch definition placement.
• The entry correctly uses backticks for the retired term (`zombie`) in historical context, keeping it as a code token rather than a reintroduced product noun, in line with AGENTS.md.

Confidence Score: 5/5

Documentation-only change that adds a single changelog entry with no logic, schema, or API modifications.

The change is a single prose block in a changelog file. No code paths, data models, or API contracts are touched. The terminology rules from AGENTS.md are respected — legacy term appears only in backticks as a retired token, not as a product noun — and the entry follows the established Update structure used throughout the file.

No files require special attention.
