Overview

This PR updates all documentation files to accurately reflect the current state of jstime's implemented APIs. The documentation had fallen behind recent feature additions, particularly for cryptography, text encoding, streams, process I/O, and JSON modules.

Changes Made

1. Updated Copilot Instructions (.github/copilot-instructions.md)

• Added missing APIs to the architecture overview:
  • streams and text_encoding to WHATWG standards
  • crypto (Web Cryptography API) to W3C standards
  • process with stdin/stdout/stderr capabilities to Node.js compatible APIs
  • date_locale polyfill documentation
• Updated dependency list with ring (0.17) for cryptographic operations and align-data (0.1.0)
• Corrected conformance test counts from 190 to 312 tests across 13 test files
• Added documentation for 5 previously undocumented conformance test suites

2. Enhanced Conformance Test Documentation (core/tests/CONFORMANCE_TESTS.md)

Added comprehensive documentation for 5 missing test suites:

• Event and EventTarget (33 tests) - DOM event handling
• Text Encoding API (39 tests) - UTF-8 encoding/decoding with TextEncoder/TextDecoder
• Structured Clone API (21 tests) - Deep cloning of complex objects
• Crypto API (17 tests) - Cryptographic operations (getRandomValues, randomUUID, subtle.digest)
• JSON Modules (12 tests) - ES module JSON imports

Updated total test count: 312 tests (was incorrectly listed as 190).

3. Added JSON Modules Documentation (docs/apis/modules.md)

• Created complete JSON Modules section with practical examples
• Documented import syntax and usage patterns for importing JSON data as ES modules
• Included examples for configuration files and array data
• Added usage notes about immutability and JSON validity requirements

4. Fixed Runtime Limitations (docs/runtime.md)

• Removed outdated claims about missing file system and process APIs (these have been implemented)
• Updated limitations section to accurately reflect current capabilities
• Revised future work section to focus on actual missing features

5. Updated Architecture Documentation (ARCHITECTURE.md)

• Corrected Rust edition from 2021 to 2024
• Updated built-in APIs diagram to include all current implementations
• Expanded API Categories with:
  • Crypto APIs as a new category
  • Streams and Text Encoding properly categorized
  • Process API with I/O capabilities
  • JSON Modules in Advanced APIs

Verification

All changes have been verified:

• ✅ All 312 tests pass
• ✅ Code formatting passes (cargo fmt --all -- --check)
• ✅ Linting passes (cargo clippy --all-targets -- -D warnings)
• ✅ Documentation consistency checked across all files

Impact

This PR makes the documentation complete and accurate, ensuring that:

• Contributors have correct information about implemented APIs
• The Copilot instructions accurately guide AI assistance
• Conformance test coverage is properly documented
• Users can discover all available features through the docs

No code changes were made - this is purely a documentation update.
