Additionally
- Include more metadata in nuget package
- Also generate snupkg for native symbols.
We intentionally don't add the symbols for native rust shared library
to the nuget package since that could increase the size of the nuget.
We will revisit that later.
- update licenses of all the bindings.

Bump up the versions to 0.9.0 to match the C# binding version.
Also use central version management for C# projects
Also fix clippy lint errors

- Introduce ExecutionTimer/ExecutionTimerConfig to allow limiting evaluating time.
- To amortize time checking costs, checking interval can be configured via the notion of work units
- A global fallback time limit can be set to universally limit all evaluation in addition to engine level limit setting.
- Implement limnits in interpreter and RVM. In RVM, also handle suspend/resume so that time during pause is not counted.
- Add engine-level APIs to set/clear per-engine timer configuration and apply global fallback defaults.
- Surface execution-time limits through FFI and C# bindings
- Add C# tests and example usage to validate engine overrides, global fallback behavior, and compiled policy enforcement.
- Expand docs for execution-time limit
- Add interpreter YAML cases and VM unit tests for time-limit behavior and deterministic time sources.

- split the xtask crate into structured modules for
- bindings
- ci
- dev
- util
- no-std
- Adding commands for
- ci-release/ci-debug
- MUSL/no-std
- per- binding language smoke tests
- developer tasks (fmt, clippy, pre-commit, pre-push)
- refresh Cargo manifests/locks, binding readmes, and shared FFI helpers so every binding reuses the same preparation steps
- refactor GitHub Actions (release/debug, extensions, CodeQL, clippy, bindings) to call the new xtask commands
- Use rust-cache in ci workflows (microsoft qdk also does this)
- extend README with a contributor workflow section describing how xtask mirrors CI expectations
- update pre-commit and pre-push hooks to use the xtask dev commands
WORKAROUND:
When dotnet is run from an xtask, codeql tracer intercepts it an routes to a nonexistent binary.
Therefore in codeql workflow, xtask is not used for c# and instead dotnet is directly invoked.

Policy evaluation at scale needs to be able to set memory limits
so that a bad policy does not hog memory or to ensure that
policy evaluation itself does not use too much memory which could
cause other components to suffer.
This PR introduces capability to set and enforce global memory limits.
It also lays the groundwork for enabling per evaluation limits in future.
Once a global memory limit is set, Regorus maintains per thread counters
to track memory activity (allocation, deallocation) of a thread.
These counters are periodically flushed to global memory counters.
Per thread counters avoid the contention that updating global counters
on each alloc/free would cause.
Policy evaluation periodically checks these counters and raises errors
if allocated memory has exceeded the configured limit.
Currently memory limit capability is exposed only to FFI and C#.
Also update mimalloc to v2.2.6

This PR implements widely accepted Rust programming practices for
dealing with panics across ABI (programming language) boundaries.
- Add panic_guard.rs to wrap FFI calls and prevent panic across FFI/ABI boundary (undefined behavior).
- Capture per-thread backtraces via a temporary panic hook
- After a panic, subsequent invocations are poisoned.
- Integrate with_unwind_guard across the engine, schema registry, and target registry exportis

- Introduce Utf8Marshaller helpers and SafeHandle wrappers so the managed API centralizes UTF-8 conversions and lifetime management for native pointers.
- Update Engine, Compiler, CompiledPolicy, SchemaRegistry, and TargetRegistry to rely on the new marshaller/safe handles, tightening disposal and reducing transient allocations during interop calls.
- Add allocation guard coverage in Regorus.Tests and report bytes/op in the compiled policy benchmark to surface future regressions.

Also update binding versions and lock files.
Note:
- Ruby binding is not updated
- C# binding is v0.7.0. We will make it match Regorus version later.

- Documentation
- Regorus Engine is intended to be used from a single thread
- Clone the engine after adding policies and data to use from another thread
- Builtin errors strictness:
- default to less strict for OPA compatibility
- Provide API to change strictness
- Expose GetAstAsJson to C#,
This can allow writing policy validations in C#.
- Use spectre mitigated msvc crt libs (binskim compliance)
- Update dependencies

Organize C# binding example into separate Regorus nuget package and
a test app.
The nuget package targets netstandard 2.0 and 2.1.
The test app is tested for netframework 8.0.
Implement IDisposable for Engine cleanup.
Also remove net40 example. Can be added back later if needed.
