Fix extraneous border gap on agent tool-call banners

[warp-dev-github-integration]

Description

Agent tool-call "banner" cards in the agent view showed a faint extraneous border with a ~1px gap between the outermost border and the banner fill, most visible at the rounded corners. It affected cards that render a rounded header/body nested inside a bordered container — shell-command cards and computer-use permission cards — but not read-file results (which auto-execute with no nested header).

Root cause: these cards wrap a rounded surface_2 header/body inside an outer Container that has a Border::all(1.) and an 8px corner radius. The nested fills kept the full 8px corner radius while the outer border insets them by 1px, so the inner rounded corners did not nest against the inner edge of the border, leaving a 1px gap that revealed the background.

Fix: shrink the nested header/body/footer corner radii to 7px (8px − 1px border) so they sit flush against the inner edge of the border — the same way a single bordered Container already composes its inner corner radius in the rect shader. This is a rendering-only change; no behavior changes and no tests added (per the report).

Changed:

• app/src/ai/blocklist/inline_action/requested_action.rs (RenderableAction::render — header + footer)
• app/src/ai/blocklist/inline_action/requested_command.rs (RequestedCommandView — header, inline editor body, MCP body, citations/profile footers)

Testing

Built and ran Warp locally (cargo run --bin warp -- --api-key $WARP_API_KEY), opened an agent conversation, and had the agent run a shell command to produce a command tool-call card. Inspected the card's rounded corners at high zoom (direct pixel capture): the card now renders as a single clean rounded rectangle — the border and fill meet flush at the corners with only normal anti-aliasing, and there is no dark gap / double edge between the outer border and the banner.

• I have manually tested my changes locally.

Overview

This PR adjusts the nested agent tool-call banner header/body/footer corner radii from 8px to 7px so their backgrounds sit flush inside the outer 1px bordered 8px container. I did not find correctness, security, or spec-alignment issues in the code diff; spec_context.md says no approved or repository spec context was found.

Concerns

• This is a user-facing UI styling change, but the attached PR description does not include an actual screenshot, GIF, video, or hosted media link demonstrating the result end to end. The checked box and textual testing notes do not satisfy the repo's visual-evidence requirement. Please attach screenshots or a short recording showing the fixed banner corners.

Thanks for the review. Update in response to the feedback:

Removed the border entirely on the finished command card (also addressing reporter feedback that the border was the same surface_2 shade as the fill it wraps, making it redundant there). The outer border is now drawn only where it does visual work — the accent highlight while the agent is awaiting permission to run a command, and outlining an inline command/MCP body. Combined with the earlier corner-radius nesting fix, the finished card is now a single solid, smooth rounded fill.

Verification (ran the app): built and ran Warp and drove the agent to run a shell command.

• Finished command card: borderless solid #242424 rounded fill on the #0c0c0c background, clean smooth corners — no gap or double-edge.
• Permission-prompt card: still shows the teal accent border (#24aeda), confirming the meaningful border is preserved.

Before/after screenshots of the running app are posted in the linked Slack thread and are visible in the Warp conversation linked in the PR description. (This PR is authored from an automated environment that can't attach binary images directly to the PR body — happy to have them inlined if required.)
