fix: unwrap ResilientProvider name in noop summarize check

[kagura-agent]

Summary

Fixes #1020.

ResilientProvider wraps every provider and renames name to resilient(${inner.name}). The noop short-circuit in mem::summarize checks provider.name === "noop", which never matches the wrapped name resilient(noop). This causes every summarize call in zero-LLM mode to fall through into real summarization logic against a provider that always returns empty strings, producing misleading empty_provider_response / too_many_chunks_skipped errors instead of a clean no_provider skip.

Changes

• src/functions/summarize.ts: Unwrap resilient(...) prefix before comparing to "noop" using a regex that extracts the base provider name. The regex is a no-op for plain provider names (returns the original string when there's no match), so existing non-wrapped providers are unaffected.
• test/summarize.test.ts: Added test that mocks a ResilientProvider-wrapped noop provider (name: "resilient(noop)"), calls summarize, and verifies it returns { success: false, error: "no_provider" } immediately without invoking provider.summarize().

Testing

• All 13 summarize tests pass (including the new one)
• Full test suite: 1415/1416 pass (1 pre-existing failure in fs-watcher.test.ts unrelated to this change)
• Build: npm run build clean

Summary by CodeRabbit

• Bug Fixes

  • Summarization now correctly detects and skips providers that are effectively unavailable, even when wrapped in a resilience layer, returning a clear “no provider” outcome instead of proceeding.

• Tests

  • Added a new test case to verify that when a resilience-wrapped “no provider” is used, summarization is not invoked and the proper failure response is returned.

📝 Walkthrough

Walkthrough

The summarize function now unwraps resilient(...) provider names before checking for noop, and the test suite includes a regression case for a wrapped noop provider that must short-circuit without calling summarize.

Changes

Noop provider detection fix

Layer / File(s)	Summary
Unwrap resilient() and verify short-circuit src/functions/summarize.ts, test/summarize.test.ts	The summarize no-provider branch now checks the underlying provider name before comparing with noop, and a regression test confirms wrapped noop providers return no_provider without invoking summarize.

Remove WHAT-comment; naming already conveys intent.

The comment restates what the code does. baseProviderName already makes the intent clear.

As per coding guidelines: "In TypeScript source code, avoid code comments explaining WHAT — use clear naming instead."

♻️ Proposed fix

-      // Unwrap resilient(...) wrapper to get the base provider name (`#1020`)
-      const baseProviderName = provider.name.replace(/^resilient\((.+)\)$/, "$1");
+      const baseProviderName = provider.name.replace(/^resilient\((.+)\)$/, "$1");

Hi 👋 Friendly check-in — this PR has been open for a week. The fix is minimal (one-line change to unwrap ResilientProvider name in the noop summarize check). Happy to adjust anything if needed!

[kagura-agent]

Addressed the CodeRabbit nitpick — removed the WHAT-comment in 7db0bb3. baseProviderName speaks for itself. 👍
