Greptile Summary

This is a housekeeping PR that adds missing LICENSE and README files, updates copyright years to 2026, and pins the hyperstack-idl crate version constraint (version = "0.1") across cli, interpreter, and hyperstack-macros. The changes are low-risk and largely additive.

Key changes:

• hyperstack-idl/LICENSE and hyperstack-idl/README.md were missing despite being referenced in hyperstack-idl/Cargo.toml (license-file = "LICENSE" and readme = "README.md"); both are now correctly added.
• version = "0.1" is added to the hyperstack-idl path dependency in three crates. The constraint resolves to ^0.1 (>=0.1.0, <0.2.0), which is compatible with the crate's actual version 0.1.1. This version field is required for publishing to crates.io.
• Copyright year updated from 2024 → 2026 in python/hyperstack-sdk, rust/hyperstack-sdk, typescript/react, and new files set directly to 2026.

Confidence Score: 5/5

• This PR is safe to merge — all changes are additive housekeeping with no functional code modifications.
• All changes are non-functional: license/README files, copyright year bumps, and a version constraint addition that is fully compatible with the existing crate version (0.1.1 satisfies ^0.1). No logic, APIs, or runtime behavior are affected.
• No files require special attention.

Important Files Changed

Filename	Overview
cli/Cargo.toml	Adds version = "0.1" constraint to hyperstack-idl path dependency; compatible with the crate's actual version 0.1.1 (^0.1 range).
hyperstack-macros/Cargo.toml	Same version = "0.1" addition for hyperstack-idl; consistent with the other crate changes.
interpreter/Cargo.toml	Same version = "0.1" addition for hyperstack-idl; consistent with the other crate changes.
hyperstack-idl/LICENSE	New MIT LICENSE file; hyperstack-idl/Cargo.toml already referenced license-file = "LICENSE", so this file was missing and is correctly added.
hyperstack-idl/README.md	New minimal README; hyperstack-idl/Cargo.toml already referenced readme = "README.md", so this file was also missing and is correctly added.
python/hyperstack-sdk/LICENSE	Copyright year updated from 2024 to 2026; year jump skips 2025, but 2026 is the current year and is valid.
rust/hyperstack-sdk/LICENSE	Copyright year updated from 2024 to 2026; same as Python SDK.
typescript/core/LICENSE	New MIT LICENSE file with copyright year 2026 added to the TypeScript core package.
typescript/react/LICENSE	Copyright year updated from 2024 to 2026, consistent with other license updates in this PR.
