fix(web): remove negative margin from agent button

[zacksmash]

Summary

• remove the -mx-1 class from the agent spawn CTA button
• keep the shared web and desktop renderer button aligned with the surrounding timeline content

Why

The negative horizontal margin extended the button beyond its containing content. Removing it preserves the existing internal padding and behavior while correcting the alignment.

User impact

The agent button now follows the container's horizontal bounds in both the web and desktop apps. Desktop bundles this web client, so no desktop-specific component change is needed. There is no interaction or behavior change.

Validation

• git diff --check upstream/main...HEAD
• pre-commit vp fmt

Note

Low Risk
Single-class CSS tweak on a timeline button with no logic or API changes.

Overview
Removes the -mx-1 Tailwind class from the timeline agent spawn CTA (AgentSpawnCtaRow) so the full-width button no longer bleeds past the content column’s horizontal bounds.

Padding, hover, and Open Agents behavior are unchanged; this only affects alignment for the shared web timeline (and desktop, which bundles the same client).
