test(vscode): dedupe childID coverage

[marius-kilocode]

Consolidates duplicated childID coverage. The extension host helper in src/kilo-provider/task-session.ts and the webview copy in webview-ui/src/context/session-utils.ts had byte-identical bodies, so the webview module now re-exports the host helper instead of keeping a second implementation. The duplicated describe("childID") block in task-session.test.ts is removed; the identical four cases still run in session-utils.test.ts through the re-export, so behavioral coverage is unchanged.

The webview already imports pure helpers from src/kilo-provider/ (command-completion), and task-session.ts has no host-only dependencies, so the cross-boundary import is safe.

Validation (from packages/kilo-vscode):

• bun test tests/unit/session-utils.test.ts tests/unit/task-session.test.ts - 98 pass, 0 fail
• bun run lint - pass
• bun run knip - pass
• bun run check-types:webview - 55 errors before and after the change (all pre-existing missing workspace modules), none in the touched files
• bun run check-types (host) - pre-existing environment errors only; none in the touched files
• bun run test:unit - pre-existing environment failures in unrelated files (missing @kilocode/kilo-memory, @opencode-ai/core/kilocode/zero-id, @xterm/xterm, etc.); the two touched test files pass

Code Review Summary

Status: No Issues Found | Recommendation: Merge

The change replaces the webview-local childID copy with a re-export of the dependency-free host helper in src/kilo-provider/task-session.ts, and drops the now-duplicate describe("childID") block from task-session.test.ts. I verified the four cases still run in session-utils.test.ts (lines 246-269) through the re-export, that task-session.ts has no host-only imports (safe for the browser webview bundle), and that all existing callers (KiloProvider.ts, session.tsx, TaskToolExpanded.tsx, subagent-tabs.ts) remain type-compatible. Behavioral coverage is unchanged.
