executus's tool.Invocation already carried InputFiles (audio/PDF/binary), but the
executor never staged them — only Images were folded into the run. This adds the
host seam mort's chat/chatbot surfaces need for audio-input parity with agentexec.
- run.Ports gains InputFiles InputFileStager (nil-safe; nil = input files silently
ignored, run still proceeds text-only). The interface mirrors mort's skill
FileStorage: StageInputFile(ctx, runID, agentID, name, mime, content) → file_id.
- run/input_files.go (ported from mort agentexec/input_files.go): stageInputFiles
persists each file under run scope and appends an [ATTACHED FILES] descriptor
block to the prompt so the agent can reach them by file_id (e.g. code_exec
files_in → /workspace/<name>). Bytes are NEVER inlined into model context.
Best-effort: empty/oversized(>50MB)/save-error files are skipped; colliding
base names are disambiguated (name-2, name-3) so they don't clobber at
/workspace/<name>.
- Executor.Run calls it after the model/toolbox build, before the loop, so the
descriptor rides the first user turn (alongside the existing Images folding).
Tests: stages + builds the block; nil stager / no files leave the prompt intact;
dedup; empty/save-error skipping. Full suite green.
