chore(bazel): build and test the foundation Rust crates - #969
CI Bazel only covered one Rust crate, so most of the workspace never benefited from its cached builds and test results. This brings the foundation crates (platform, ARD, A2A pack and redaction, decider core and WIT, AAuth verifier) under Bazel. They have no build scripts and sit at the bottom of the dependency graph, so they are the cheapest place to start. Cargo is unchanged.
workspace_crate in .config/bazel/rust.bzl declares a crate's library, unit tests, and one target per integration test, taking external dependencies from its Cargo.toml.
Tests that start NATS through Docker run as they do under Cargo. Tests that read sources outside their package are tagged manual; trybuild and the WIT feature build shell out to Cargo and have no Bazel target.
Seven a2a-redaction unit tests read fixtures through the compile-time CARGO_MANIFEST_DIR, which points into the build sandbox under Bazel, so they are skipped there and keep running under Cargo.
The CI Bazel path filter and docs/how-to/use-bazel.md cover the new crates.
Note
Low Risk
Mostly build-graph and CI wiring; no production runtime paths change, though broader bazel test //... may surface flaky or network-tagged tests in CI.
Overview
Expands Bazel coverage from a single curated //.config/bazel:build filegroup to all targets (//...), and adds a shared workspace_crate macro in .config/bazel/rust.bzl that declares each Cargo package’s library, unit tests, and per-file integration tests (external deps still come from Cargo.toml via crate_universe).
Foundation Rust crates (platform, ARD, A2A pack/redaction, decider, AAuth verifier, etc.) now have BUILD.bazel files wired through that macro; trogon-config-value is migrated off hand-written rust_library/rust_test targets. a2a-redaction WASM unit tests embed their fixture with include_bytes! so they work in Bazel’s sandbox, and the crate exposes extra Bazel targets for the a2a-sign-bundle binary and its test.
Mise Bazel tasks, the CI Bazel workflow build step, and docs are updated to build/query the full graph; the workflow path filter now triggers on rsworkspace/crates/** instead of only trogon-config-value.

CI Bazel only covered one Rust crate, so most of the workspace never benefited from its action and repository caches. The foundation crates have no build scripts and sit at the bottom of the dependency graph, so migrating them first extends coverage without touching Cargo.
A single workspace_crate macro replaces per-crate library, unit test and integration test boilerplate. Tests that start NATS through Docker run as they do under Cargo; tests that read sources outside their package are tagged manual.

The pull request adds a reusable Bazel macro for Rust crates and applies it to workspace targets. It also updates the Bazel build filegroup, CI path filters, and documentation to cover the added crates and their tests.
The new workspace_crate macro declares library, unit-test, and integration-test targets with configurable dependencies and attributes. The trogon-config-value BUILD file now uses the macro.
Bazel targets are added for platform crates, including their specified dependencies, features, data, and integration tests.
Workspace targets and CI registration rsworkspace/crates/a2a/*/BUILD.bazel, rsworkspace/crates/aauth/*/BUILD.bazel, rsworkspace/crates/ard/*/BUILD.bazel, rsworkspace/crates/decider/*/BUILD.bazel, .config/bazel/BUILD.bazel, .github/workflows/ci-bazel.yml, docs/how-to/use-bazel.md
Additional A2A, authentication, ARD, and decider targets are declared. The build filegroup and CI path filters include Rust crates. The guide describes crate setup and test selection.
TrogonStack/trogonai#960: Establishes the Bazel migration, CI workflow, and initial Rust crate target that this pull request extends.
TrogonStack/trogonai#860: Adds the trogon-claude-agent-sdk crate, which this pull request configures for Bazel builds and integration tests.
Merge Risk: Low · previous review d202c
The Bazel build and test wiring is generally sound. One explicitly runnable source-policy test cannot pass under Bazel, and seven fixture-dependent tests are skipped there. Both gaps are limited to Bazel test coverage; Cargo still runs those tests. Address them or accept the limitation knowingly.

A rabbit checks the BUILD file twice, Then adds crate targets neat and nice. The test paths hop into the line, The CI filters follow fine. A carrot waits; the builds all shine.
A rust_test with a crate attribute compiles the crate again and reads features from its own attributes, so code behind features such as test-support was missing from unit tests. Docker-backed trogon-nats tests are tagged requires-network so the requirement is explicit to Bazel.

Review comments at @rsworkspace/crates/a2a/a2a-redaction/BUILD.bazel:
- Around line 11-18: The Bazel unit-test configuration skips seven
bundle-loading and signature-validation tests because their fixtures are
inaccessible. Update the fixture access used by the relevant tests in
`wasm::tests` to embed the fixture or resolve it through Bazel runfiles, then
remove the corresponding `--skip` arguments from `unit_test_args` so these tests
run under both Bazel and Cargo.
Review comments at @rsworkspace/crates/platform/trogon-nats/BUILD.bazel:
- Line 12: Update the Bazel test target associated with subject_literal_policy
to declare the scanned source files as runtime inputs and resolve them through
Bazel runfiles at test execution. Replace reliance on the compile-time
CARGO_MANIFEST_DIR path so the explicit source-policy test runs by label in a
sandbox.

The wasm tests read their fixture from the source tree at runtime, so
Bazel had to skip seven of them. Embedding the fixture removes the
runtime path and lets them run everywhere.
trogon-nats subject_literal_policy scans sibling crate sources, which
Bazel cannot see, so it no longer gets a target that only runs by hand.

Every new crate had to be added to an aggregate filegroup and to the
CI Bazel path filter. Building //... and triggering on any crate change
makes a crate's own BUILD.bazel the only file to touch.
