pkg/aflow: abstract LLM provider Decouple the aflow package from the google.golang.org/genai library to enable future integration with other LLM providers (e.g., Claude). Introduce a generic backend.Provider interface and corresponding types (Message, Part, GenerateConfig, etc.) in pkg/aflow/backend. Move the existing Gemini-specific logic into pkg/aflow/backend/gemini, which now implements this interface. Update the core aflow execution logic and agents to rely solely on the generic backend types. Finally, update syz-agent and tools/syz-aflow to explicitly initialize the Gemini provider and inject it into the workflow execution.

dashboard/app: use helper methods for AI job and report polling Reduce boilerplate in dashboard AI test cases by consolidating agent and report polling into helper methods. Manually constructing poll requests and confirmation payloads across test functions makes the test suite verbose and harder to maintain. Replace repetitive agent and report polling checks with pollAIJob, pollAIWorkflow, pollAndConfirmReport, and assertNoPendingReport.

pkg/aflow: support Suggested-by tags in patch iteration workflow Credit reviewers who provide idea suggestions during automated patch review. Support extracting and preserving Suggested-by tags across patch iterations and include them when rendering patch commit descriptions.

syz-cluster: provide on-demand patch testing Enable patch authors to request syz-cluster fuzzing without sending the patch to the public mailing lists. Guarantee evaluation and reporting for series explicitly sent to our direct mailing list. Introduce a `Direct` flag for such sessions. Use this flag to bypass AI triage, prioritize the session in the queue, and ensure an email report is sent even if no bugs are found.

dashboard/app: allow disabling AI comment replies per stage Automatic comment replying is still an experimental feature. We want to avoid sending unmoderated text replies to public mailing lists, and for now it is cleaner to only allow conversational replies during the moderation stage. This also simplifies the overall implementation of #7671. Add a ReplyToComments configuration option to AIPatchStageConfig. When disabled for a stage, pass the flag to the patch iteration workflow to skip generating text replies and suppress creating external report entries if no new patch version was produced.

dashboard/app: add AI jobs statistics graphs page Provide monthly visualization charts for AI token consumption per model, finished job counts, and job type distributions to track LLM usage and agent workload trends. Aggregate token spans and jobs by month in Spanner queries, expose charts to admins via Google Charts, and add unit tests for graph builders and endpoint access control.

pkg/aflow/flow/patching: add patch refinement loop for formatting Ensure generated kernel patches comply with kernel coding standards and checkpatch.pl before completion or resubmission. Add checkpatch and clang-format tools. Remove mandatory clang-format-diff.py from crash.TestPatch in favor of tool-based formatting. Introduce patchRefinementLoop in formatting.go to run checkpatch.pl after patch generation and delegate style fixes to a patch-formatter agent. Update verdictAgent to separate StyleItems from CodeItems. Export sandboxed patchdiff.Diff.

pkg/cover/backend, pkg/aflow: resolve source lines to coverage PCs Workflows like seed generation need to determine which KCOV coverage callbacks cover a given file and line. Previously, seedgen parsed DWARF line tables independently, duplicating logic already available in pkg/cover/backend. Add ResolveLineToPCs to backend.Impl to map a file and line number to its covering basic block entry PC. Switch seedgen to this method and remove its duplicate DWARF parsing.

pkg/execbackend: add RunLocal testing helper and rpc test Introduce execbackend.RunLocal along with a local VM implementation to allow running tests natively using the execbackend abstraction. This simplifies the setup by handling VM creation and server setup under the hood. Update TestFuzz in pkg/fuzzer/fuzzer_test.go to use execbackend.RunLocal instead of rpcserver.RunLocal, making the test much simpler and validating the new execbackend abstraction. Add TestRPCBackendLocal in pkg/execbackend/rpc_test.go to directly test the execbackend execution loop and connection handshake with the executor.

pkg/clangtool: fix C++ static constructor interception race Intercepting tool execution via C++ static constructors causes the clang tools (e.g., codesearch) to run before the Go runtime is fully initialized. This early execution leads to unpredictable initialization races when interacting with complex libraries like LLVM. Fix this by moving execution into an auto-intercepting Go registry. Tools now register themselves via `clangtool.Register` in a CGO `init()` function, which immediately executes the tool via `extern "C"` if requested. This guarantees the Go runtime has booted safely. If a requested tool is not compiled in, `runTool` will now return an error before attempting to spawn the subprocess.
