feat(vscode): show thread git metadata

[Hmbown]

Summary

• parse head and dirty from runtime thread summaries in the VS Code Agent View
• render branch/head/dirty metadata in the thread row without adding mutation endpoints
• mirror the v0.9 changelog credit for the IDE/Agent View request trail

Verification

• npm ci && npm run check (extensions/vscode)
• npm run package (extensions/vscode)
• ./scripts/release/check-versions.sh
• git diff --check

Credit

Thanks @AiurArtanis and @nasus9527 for the IDE/agent-view requests, and @gaord for the runtime metadata direction in #2808/#2862.

Code Review

This pull request adds support for rendering Git metadata, specifically the commit head and a dirty worktree flag, alongside branch metadata in the VS Code Agent View. The feedback suggests simplifying the parsing logic in runtime.ts by checking record.dirty === true directly, which would render the new readBoolean helper redundant. Additionally, it is recommended to truncate the thread.head value to a 7-character short SHA if it is a full 40-character Git commit SHA to prevent layout clutter in the VS Code sidebar.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

We can simplify this by checking record.dirty === true directly, which is consistent with how archived is handled on the next line. This also makes the helper function readBoolean redundant, allowing us to remove it entirely.

Suggested change

	dirty: readBoolean(record.dirty),
	dirty: record.dirty === true,

[gemini-code-assist]

Since we can check record.dirty === true directly (similar to record.archived === true), this helper function is no longer needed and can be safely removed.

If thread.head is a full 40-character Git commit SHA, displaying it in its entirety can cause awkward text wrapping and clutter the narrow VS Code sidebar (Agent View). Truncating it to a standard 7-character short SHA when it matches a full SHA pattern improves readability and layout density.

Suggested change

	if (thread.head) {
	parts.push(`@ ${thread.head}`);
	}
	if (thread.head) {
	const shortHead = /^[0-9a-f]{40}$/i.test(thread.head)
	? thread.head.slice(0, 7)
	: thread.head;
	parts.push(`@ ${shortHead}`);
	}
