Commit 250bf6edd renamed KHASH_DEFAULT_SIZE to KHASH_INITIAL_SIZE but
missed updating build_config files and documentation. Also restore the
default value in khash.h to 32, consistent with the documented default
and the profile hierarchy (MRB_CONSTRAINED_BASELINE_PROFILE reduces it
to 16).
Change default stack growth from linear (+128) to exponential (1.5x).
This reduces reallocation frequency while maintaining reasonable memory
usage. The minimum growth is still MRB_STACK_GROWTH (128) to ensure
small programs don't over-allocate.
MRB_STACK_EXTEND_DOUBLING (2x growth) remains available for maximum
performance when memory is not a concern.

The documentation table is generated by the `rake doc:update-index` command.
The following conditions must be met for links to be added to the documentation table.
- The file must be placed under the `doc/` directory
- The file must have the extension `.md`
- The file must be written at the top of the file with `<! -- summary: ANY-TEXT -->`
The purpose is to remove the `mid` field from the `mrb_cache_entry` structure.
The resulting RAM requirement for the method cache is reduced from 5 words per entry to 4 words per entry for 32-bit CPUs.
The relevant changes are as follows:
- Removed `MRB_USE_METHOD_T_STRUCT`.
The `mrb_method_t` type is now always defined as a structure.
- Include method IDs in `mrb_method_t`
Change the `flags` member to `uint32_t`.
The bitstring structure should be the same as the keys of the `mt` table in `class.c`.
I believe the impact on API compatibility with previous versions is minimal.
The correct technique now is "Token Threading".
However, the new name was chosen because it was felt that if a different technique was added in the future, there would be no need to replace it.
* use predefined `mrb_ro_data_p()` for user-mode Linux and macOS
* define `MRB_LINK_TIME_RO_DATA_P` if predefined one is used
* configure macro `MRB_USE_LINK_TIME_RO_DATA_P` is no longer used
* contributions for new platforms are welcome

Added the GitHub Super Linter badge to the README.
Also updated the pre-commit framework and added
more documentation on pre-commit.
Added one more pre-commit check: check-executables-have-shebangs
Added one extra check for merge conflicts to our
GitHub Actions.

- `MRB_WITHOUT_FLOAT` => `MRB_NO_FLOAT`
- `MRB_USE_FLOAT` => `MRB_USE_FLOAT32`
The former is to use `USE_XXX` naming convention. The latter is to make
sure `float` is 32bit float and not floating point number in general.
Introduced `MRB_NO_METHOD_CACHE` which is inverse of `MRB_METHOD_CACHE`
that should be enabled intestinally. In addition, the default cache is
made bigger (128 -> 256).
In lld linked programs, .rodata comes before .text, thus mrb_ro_data_p
will return false for strings in .rodata. Change the lower bound from
_etext to __ehdr_start to catch these cases. This works for ld.bfd, gold
and lld, and it does not have false positives even if .init_array does
not exist.
Remove the branch that uses _edata: strings in .data can be modified so
this is semantically incorrect. Delete the __APPLE__ branch (its
manpages say get_etext() and get_edata() are strongly discouraged).
.init_array has been adopted by most ELF platforms to supersede .ctors.
Neither _etext nor _edata is used, so rename MRB_USE_ETEXT_EDATA to
MRB_USE_EHDR_START.
`MRB_METHOD_TABLE_INLINE` was fragile. It requires `-falign-functions=n`.
On platform that uses higher bits of function pointers, you can use new
`MRB_METHOD_T_STRUCT` configuration macro.
