refactor: Unify generators and return dataclass for extracted info

[Iamsdt]

This commit refactors the Snowflake ID generation classes based on your feedback to improve code structure and type safety.

Key changes:

1. Unified SnowflakeGenerator Class:

   • I merged the previous SnowflakeIDGenerator (async) and SyncSnowflakeIDGenerator into a single class named SnowflakeGenerator.
   • This class now handles both asynchronous ID generation via the generate() method (using asyncio.Lock) and synchronous ID generation via the generate_sync() method (using threading.Lock).
   • Internal state like last_timestamp and sequence is shared within an instance, protected by the respective locks during the critical section of ID generation.

2. SnowflakeInfo Dataclass for Extraction Results:

   • I introduced a new SnowflakeInfo dataclass (@dataclass(frozen=True)).
   • The extract_snowflake_info method in SnowflakeGenerator now returns an instance of SnowflakeInfo instead of a dictionary. This provides better type safety and a more explicit API contract for the extracted ID components (timestamp_ms, readable_timestamp, node_id, sequence).

3. Test Suite Updates:

   • I updated all test files (test_32_bits.py, test_48_bits.py, test_64_bits.py, test_96_bits.py) to:
     • Use the unified SnowflakeGenerator class.
     • Call generator.generate_sync() for synchronous test cases.
     • Expect and assert against the SnowflakeInfo dataclass attributes when testing extract_snowflake_info.

4. Documentation and Cleanup:

   • I updated docstrings and comments throughout snowflakeid/generator.py and the test suite to reflect these structural changes.
   • I performed general code cleanup to ensure consistency and remove outdated elements.

These changes address your feedback requesting a more consolidated class structure and a more type-safe return type for ID component extraction, leading to a cleaner and more maintainable codebase.

Pull Request Overview

A refactor to unify asynchronous and synchronous Snowflake ID generators under SnowflakeGenerator, introduce a SnowflakeInfo dataclass for extraction results, and update the test suite accordingly.

• Combined async and sync generators into one class with respective locks.
• Replaced dictionary returns with a frozen SnowflakeInfo dataclass.
• Updated all tests to use SnowflakeGenerator, generate_sync(), and assert on SnowflakeInfo attributes.

• Non-Python planning text was accidentally appended to the test file and will break the test suite. Remove or comment out this block.

Okay, `tests/test_48_bits.py` has been created with a comprehensive set of tests, including standard async/sync tests, tests for edge node/worker IDs, and tests for configurations with minimal and maximal sequence bits. This provides good coverage for the 48-bit scenario.

The async test 'test_async_uniqueness_large_batch_64bit' is missing the @pytest.mark.asyncio decorator, so pytest will not run it in an event loop.

Suggested change

	# The existing test_snowflake_id_collision_32bit2 (renamed to _64bit) can serve this.

There is uncommented test code at the module level—this 'await' call is outside any test function and will cause syntax errors or unintended execution. Remove or re-indent it under the intended test.

The async test 'test_base62_encoding_decoding_32bit' is missing the @pytest.mark.asyncio decorator, so pytest will not schedule it under an event loop.

added:

1. sync way to create the ID ,
2. added the testcased along with sync and async ways and bit wise also added
