release/v2.0.1

[melbasiouny-riverside]

• Widen HToken.len and bits_env.length from uint8_t to size_t, fixing Integer Truncation in h_token Allows Parser Bypass (/src/parsers/token.c) #3. h_bits(264, false) no longer silently wraps to h_bits(8, false). For HToken, sizeof(HToken) is unchanged on common targets as the trailing struct padding absorbs the difference.
• Introduce HAMMER_ASSERT in internal.h and replace assert()-based programmer-error guards across bitwriter.c, glue.c, glue.h, and datastructures.c, closing assert() used as sole input validation which is silently disabled under -DNDEBUG #6. Unlike assert(), HAMMER_ASSERT always aborts regardless of -DNDEBUG. Runtime boundary conditions such as the sloballoc size check retain explicit safe returns.
• Update h_assert_type macro to use HAMMER_ASSERT, aborting on type mismatch in all builds.
• Update test_token_len_assert to reflect the new behavior: tokens longer than 255 bytes are now valid, and the test verifies a 256-byte token parses correctly end-to-end.
• Add ruff linting of Python and SCons files to the CI pipeline alongside other formatting checks before the build-deb step.

We should investigate how we want to go about replacing the asserts. Some cases returning NULL, 0, etc may be appropriate or calling abort() may be the appropriate.

I think utilizing a fixed size data structure instead of size_t could be valuable and we should also consider keeping in asserts for debug builds to give rich error messages

Thanks for your feedback @jhjones-riverside and @GJames-RiversideResearch. I agree that a blanket silent-fail approach isn't ideal. I'm thinking of adding a HAMMER_ASSERT macro that always calls abort() regardless of -DNDEBUG for programmer-error guards, while keeping explicit safe returns for true runtime boundary conditions like the sloballoc size check. Open to other approaches if you all have something else in mind.

Looks good with 1 slightly pedantic comment
