fix(dapi): files generated outside sandbox

[lklimek]

Issue being fixed or feature implemented

Codex in dash-evo-tool fails to build the project due to:

  thread 'main' (49219) panicked at /home/lklimek/.cargo/git/checkouts/platform-7a21f318038a582f/98a0ebe/packages/dapi-grpc/build.rs:38:10:
  generate core proto: Os { code: 13, kind: PermissionDenied, message: "Permission denied" }

What was done?

Fixed generated code output dir to move it into the sandbox (env var DAPI_GRPC_OUT_DIR or OUT_DIR/dapi_grpc)

How Has This Been Tested?

Let codex build dash-evo-tool using this branch.

Summary by CodeRabbit

• Chores

  • Improved build configurability: build output directory can now be driven by an environment variable with clearer error guidance and better change detection during builds.
  • Generated code output is organized into distinct subdirectories for core, platform, and drive to simplify artifacts.

• Tests

  • Internal test iteration logic simplified for clearer test flows.

📝 Walkthrough

Walkthrough

Build resolves an output base dir at build time (DAPI_GRPC_OUT_DIR fallback) and passes it into gRPC code generation; generated output paths and compile-time includes are relocated under that output base. A small loop change was made in strategy-tests addressing output indexing.

Changes

Cohort / File(s)	Summary
Build script & codegen packages/dapi-grpc/build.rs	Add resolve_output_base() returning a PathBuf; read DAPI_GRPC_OUT_DIR with fallback to OUT_DIR/dapi_grpc; change generate_code(typ) → generate_code(typ, output_base: &Path); pass output_base to Server/Client/Wasm generators; construct outputs with output_base.join(...); add cargo:rerun-if-env-changed=DAPI_GRPC_OUT_DIR; add missing env and Path imports.
Runtime/module includes packages/dapi-grpc/src/lib.rs	Replace static include! paths with compile-time concatenation using concat!(env!("DAPI_GRPC_OUT_DIR"), "...") for core, platform, and drive modules across server, client, and wasm32 targets.
Test logic tweak packages/strategy-tests/src/lib.rs	Change an output-generation loop to use enumerate() (for (outputs_created, _) in (0..output_count).enumerate()), remove manual counter increment; adjusts index usage for outputs.

Poem

🐰
I hopped through build scripts, nose aglow,
Found output burrows where the gRPC files go.
Paths now follow a tuneful, env-sent beat,
Modules include from under my feet —
A little hop, and everything's neat! 🥕

In `@packages/dapi-grpc/build.rs`:
- Line 39: Change the generate_code signature to accept an &Path instead of
&PathBuf to satisfy clippy::ptr_arg: add use std::path::Path; and update fn
generate_code(typ: ImplType, output_base: &Path) { … } and then update any
callers that currently pass a PathBuf (e.g., variables named output_base) to
pass output_base.as_path() or borrow as a Path; ensure references to the
parameter inside generate_code still work with &Path.
