This patch removes the per-line cursor cache (`line->cursor`),
reducing implementation complexity. Vertical cursor movement (up/down)
now uniformly places the cursor at the beginning of the line, instead
of trying to restore the previous horizontal position. UX
considerations such as column preservation will be revisited after
core stabilization.

This adds `line_get_slice` and `eb_get_line_slice`, enabling
slice-style (pointer + length) access to line contents without
requiring materialization into a null-terminated string.
- `line_get_slice` returns either the original mmap'd buffer (if the
- line is lazy) or the materialized vector contents (if edited).
- `eb_get_line_slice` wraps `line_get_slice` to provide safe access at
- the editor buffer level. Update `line.h` and `editor.h` headers to
- declare the new functions. Minor documentation improvements to
- clarify "init", "modify", and "get" function categories.
This prepares the codebase for transitioning away from C-string
dependency where possible, improving efficiency and avoiding
unnecessary memory copies.

fix `line_cat` to handle lazy-loaded `src` line too
[minor]
add const keyword for line_get_last since it is.

vec_len is O(1) and it would be fast enough to use it.
introduce line_lazy_init for lazy load (allocate each line when
actually edit it!) per line.
[minor]
remove obsolate line_delete_trailing.

implement line_init_from_buf for this.

line_cat should be implemented; markd it TODO
|

makefile now handle each object and sources seperately to handle
header change gracefully.
and from now on, #DEBUG should declared inside of config.h

I move around most of because it did not update eb->cur_col correctly.
implement line_split which use vec_split for it
[minor]
implement eb_get_line and eb_line_num
refactor main routine to use them
add DEBUG symbol to makefile and remove lines.o for OBJS
move declaration struct line to line.c from line.h for enhanced OOP

- Fixed incorrect `MemAlloc(sizeof(type *))` usage to properly allocate `sizeof(type)` for vector structs.
- Corrected `memmove` call in vector insert to account for type size and copy full range.
- Added `line_set_cursor()` to set line's cursor position before inserting new lines.
- Replaced `line_arr` with `line_vec` in editor buffer for clearer naming.
- Improved `DrawText` fallback behavior for NULL lines.

- Rename vector type VEC -> Vec_char for clarity
- Update line.c to use renamed Vec_char API
- Add `line_insert` function for character insertion at arbitrary positions
- Define Vec_slinep as vector of line pointers in main.c
- Introduce `struct ed_buf` as an abstraction for a text buffer
- Implement `eb_insert`, `eb_free` and stub `eb_newline`, `eb_backspace`
- Update main loop to use `ed_buf` instead of standalone line/lines
- Fix vector insertion logic to support gaps and non-contiguous positions
- Change optimization level in makefile to -O0 for easier debugging

* vector.h: Add DEFINE_VECTOR macro for a header-only generic vector template
- Implements common operations: init, push, pop, set, get, len, grow
* line.[ch]:
- Replace fixed char-only vec with VEC (DEFINE_VECTOR(char)) instance
- Refactor memory allocation and method calls to use VEC_* macros
* makefile:
- Remove vec.o from OBJS (vec module is no longer used)
* vec.[ch] is now obsolete; new vector types (e.g., line *) can be defined
easily using a single DEFINE_VECTOR invocation

- Moved line-related functions (init, append, clear, delete, free) out of main.c
- Created new files: line.c and line.h to encapsulate `struct line` and its operations
- Updated main.c to use the new line module
- Simplified main.c by removing inline struct and function definitions
- Adjusted makefile to compile line.o
