fuzzer: improve proptest coverage for CLI config parsing 🌪️#2671EffortlessSteven wants to merge 1 commit into

Adds parameter and overlay-logic property fuzzing to `cli_parser_properties.rs`. Ensures CLI enum bindings and config precedence ladders are completely panic-free and predictable under arbitrary scalar limits.

If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based credits. 🚦 How do rate limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan refill rate. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, the refill rate gradually slows as usage increases. The highest same-day bursts are limited more strictly.

Code Review
This pull request introduces several property-based tests (fuzzing) to verify CLI parsing and configuration resolution logic, while cleaning up unused native bridge, UI, and runner check scripts. The reviewer recommended adding an assertion for the top field in the module configuration fuzz test to ensure its resolution logic is fully verified.

In config_resolve_fuzz_module, cli_top is generated by the proptest strategy and passed to CliModuleArgs, but its resolved value is never asserted. Adding an assertion for resolved.top ensures that the fallback logic for top is also verified in this test case.

[P0] Deleting this fixture breaks 4 compile-time include_str! sites and 1 xtask assertion
The file is consumed via include_str! at crates/tokmd-analysis/src/ast/registry.rs:423 and :657 (inside extracts_typescript_review_facts_from_native_boundary_fixture and a parameterized review-signals test), at crates/tokmd/tests/cli_syntax_integration.rs:12 (the syntax_command_emits_scoped_review_signals integration test), and the workspace test syntax_native_boundary_fixture_exists_for_nix_checks in xtask/tests/release_source_closure_w101.rs:30-39 explicitly asserts this file exists. include_str! is resolved at compile time, so removing the file makes the tokmd-analysis lib test build, the tokmd test build (with --features ast), and the xtask release_source_closure_w101 test suite all fail. Verified locally: cargo test -p tokmd-analysis --features ast --no-run and cargo test -p xtask --test release_source_closure_w101 both fail on this head SHA.

[P0] Deleting this fixture breaks a compile-time include_str! in the AST registry
crates/tokmd-analysis/src/ast/registry.rs:500 embeds the file via include_str!("../../../../fixtures/syntax/typescript/component.tsx") inside the extracts_tsx_exports_and_cast_seams test. Because include_str! is resolved at compile time, the tokmd-analysis lib test build fails after this deletion (confirmed via cargo test -p tokmd-analysis --features ast --no-run). The proptest additions in this PR are unrelated to TSX AST coverage, so this deletion looks like accidental scope creep that blocks the workspace from compiling.

[P0] Deleting this fixture breaks 2 compile-time include_str! sites in the AST registry
crates/tokmd-analysis/src/ast/registry.rs:594 (inside extracts_python_review_facts_from_native_boundary_fixture) and crates/tokmd-analysis/src/ast/registry.rs:674 (parameterized review-signals test) both embed the file via include_str!("../../../../fixtures/syntax/python/native_boundary.py"). include_str! requires the path to resolve at compile time, so removing the file breaks the tokmd-analysis lib test build (confirmed via cargo test -p tokmd-analysis --features ast --no-run). The fixture is also documented as a required input in docs/releases/1.13-readiness.md and docs/releases/1.13-dogfood.md, so dropping it without updating the test or docs creates a silent coverage regression on top of the build failure.

[P0] [security] Deleting this script breaks CI and removes a supply-chain runner guard
.github/workflows/ci-policy.yml:33 runs the script verbatim as the no-bare-self-hosted job: run: scripts/check-no-bare-self-hosted.sh .github/workflows. Removing the script causes that job to fail with No such file or directory on every push and PR to main. The script also enforces a documented supply-chain policy: it blocks runs-on: self-hosted (scalar) and bare self-hosted / linux / x64 blocks without an em-ci-* group or named capacity label, and it forbids repository-scoped runner discovery. Deleting it without a replacement regresses policy/ci-lane-whitelist.toml:542 (proof obligation Run scripts/check-no-bare-self-hosted.sh .github/workflows.) and the ci/proof.toml:168 source-closure entry that lists the script as a workspace artifact, both of which still reference the path. The proptest additions in this PR have no relationship to the runner-routing policy, so the deletion appears to be accidental scope creep.

Improved test coverage for CLI configuration parsing and logic by introducing four new property tests. These tests fuzz combinations of CLI arguments with TOML definitions and profile overlays to ensure that the CLI doesn't panic on invalid enums, and that fallback resolution respects priority ordering cleanly.

Note
Low Risk
Changes are test-only plus deletion of fixtures and a CI lint script; no production CLI or resolver logic is modified in this diff.
Overview
Adds property-based coverage in
cli_parser_properties.rsso the CLI stays panic-free when enum-like flags (--config,--format,--children,--redact) get arbitrary values, and so config merge behavior matches expected precedence.New proptests assert
