- steps: independent, run in parallel when annotated safe, outputs
concatenated. No stdout chaining.
- pipe: explicit pipeline, sequential, stdout of each stage feeds
stdin of the next.
steps and pipe are mutually exclusive in a single execute_code call.
steps is always a pipe (sequential, stdout chains to next stdin).
Concurrent fan-out requires explicit use of the parallel field.
The ollie:parallel annotation still drives agent-level tool call
parallelism via IsParallelRead, but no longer hijacks pipe semantics.
Covers detectParallelClass, sanitizeLockName, acquireFlock, classifyStep,
SetLockDir, and runReadBatch — bringing pkg/tools/execute from 70.9% to 92.4%.

- Add contract tests for tools.Server and tools.Dispatcher interfaces
(tools_test.go), covering all exported behavior including error paths.
pkg/tools coverage: 0% -> 100%.
- Add contract test for execute.Server (ListTools, CallTool), Decl
factory test, and executeElevated early-exit test. execute coverage:
68% -> 71%.
- Remove Close() from Server and Dispatcher interfaces and all
implementations/callers. These existed for MCP server cleanup which
has been removed.
