Move non-function declarations from .c files to *.internals.h headers

[Copilot]

Non-function declarations (static variables and includes) were scattered in .c files instead of being consolidated in their corresponding *.internals.h headers, inconsistent with the project convention.

Changes

• hhss/c/rtdbparse.c → rtdbparse.internals.h: moved #include <setjmp.h> and static jmp_buf env;
• lib/wrappers.c → wrappers.internals.h: moved static const char *realloc_errmsg and static const char *vfprintf_errmsg; added STATIC VARIABLES section
• lib/readline.c → readline.internals.h: moved static const char *errmsg; added STATIC VARIABLES section

Before (rtdbparse.c):

#include "rtdbparse.h"
#include "rtdbparse.internals.h"

#include <setjmp.h>

static jmp_buf env;

extern array_t *rtdbparse(array_t *linestr) { ...

After (rtdbparse.c):

#include "rtdbparse.h"
#include "rtdbparse.internals.h"

extern array_t *rtdbparse(array_t *linestr) { ...

Each *.internals.h is included by exactly one translation unit, so moving statics into them is safe and consistent with the existing pattern in files like lex.internals.h.

Pull request overview

This PR standardizes the placement of module-local declarations by moving non-function declarations (includes and static variables) out of .c files and into their corresponding *.internals.h headers, aligning these modules with the existing “single translation unit + internals header” pattern used elsewhere in the codebase.

Changes:

• Move realloc_errmsg / vfprintf_errmsg static error strings from lib/wrappers.c into lib/wrappers.internals.h.
• Move errmsg static error string from lib/readline.c into lib/readline.internals.h.
• Move <setjmp.h> and static jmp_buf env from hhss/c/rtdbparse.c into hhss/c/rtdbparse.internals.h.
