f0858b0d38 Document what the functions actually do instead of that they can fail
The Doxygen comments were generated from the declarations, so 217 @throws
lines across 21 headers read "When the corresponding validation or operation
fails" and told a caller nothing beyond the status name. The @param lines were
the same shape: every output was "Output destination populated by the
function", every instance "Object to initialize, inspect, or modify".

Rewritten against the implementations, following the pattern libakstdlib
already uses:

- @throws names the condition. akgl_sprite_load_json separated AKERR_KEY
  (absent) from AKERR_TYPE (present, wrong type) from AKERR_OUTOFBOUNDS
  (filename too long, or array indexed past its end), and gained AKGL_ERR_SDL
  and AKGL_ERR_HEAP, which it raises and never declared.
- Parameters say whether they are required, what a NULL means, and what is
  written on a failure path. Where an argument is not checked, the doc says so:
  akgl_heap_next_actor's dest is a crash on NULL, not an error, and
  akgl_render_2d_frame_start dereferences self before testing it.
- The conventions move up to the file blocks so the per-function docs stay
  short. json_helpers.h states once that absence is an error here and that
  json_t * results are borrowed; heap.h explains the pool model and the
  acquire asymmetry; physics.h carries the thrust/environmental/velocity table.
- Struct fields, enum values, macros and exported globals are documented,
  including the dead ones - sprite_w/sprite_h, movetimer, p_scale and
  timer_gravity are read by nothing, and say so.

Also fixes ten comments in error.h and audio.h that opened with /** rather
than /**<, so Doxygen attached them to the following entity and rendered the
text as part of the macro's value. Verified against the generated HTML.

Comments only - no declaration changed. Doxygen builds clean under
WARN_AS_ERROR, scripts/reindent.sh --check passes, 19/19 suites pass.

996cacb10c Consume libakstdlib 0.2.0
Some checks failed
libakgl CI Build / cmake_build (push) Failing after 19s
libakgl CI Build / mutation_test (push) Failing after 17s
Pass fixed buffer sizes to the bounded formatting and realpath wrappers. Route save-game records through exact-transfer helpers so the required fread/fwrite count parameter stays local to the complete-record contract.

9b124f2e27 Migrate to the libakerror 1.0.0 status registry
libakerror 1.0.0 replaced the consumer-sized status-name array with a
private registry and made status-code ownership explicit and enforced.
AKERR_MAX_ERR_VALUE and __AKERR_ERROR_NAMES are gone, and the registry
entry points raise akerr_ErrorContext * instead of returning int. See
deps/libakerror/UPGRADING.md.

The break was not only source-level. libakgl's codes sat at
AKERR_LAST_ERRNO_VALUE + 18 through + 22, and 1.0.0 claimed exactly
those five offsets for its own AKERR_STATUS_* registry codes, so every
AKGL_ERR_* was aliasing a libakerror status. HANDLE(e,
AKGL_ERR_LOGICINTERRUPT) at physics.c:222 would have swallowed a
foreign-name refusal.

- Move the band to AKERR_FIRST_CONSUMER_STATUS (256) as fixed offsets,
  so a libc that grows an errno cannot move the codes, and add
  AKGL_ERR_OWNER, AKGL_ERR_LIMIT and AKGL_ERR_COUNT to describe it.
- Reserve the range and register the names through the owned entry
  points, PASS-ing each: these are AKERR_NOIGNORE, and the old
  akerr_name_for_status calls discarded failure silently.
- Drop the AKERR_MAX_ERR_VALUE=256 compile definition.
- Guard on AKERR_FIRST_CONSUMER_STATUS in include/akgl/error.h, which
  now includes <akerror.h> so the guard is reliable. The embedded build
  is fine, but the find_package path can pick up a stale installed
  header, and 1.0.0 has an soname, so that pairing is an ABI mismatch
  rather than a compile problem. Same guard libakstdlib already carries.

Registration also moves out of akgl_heap_init into a new akgl_error_init
in src/error.c. It was in the heap pool's initializer only because that
was the first thing akgl_game_init called, and the upgrade turned five
fire-and-forget name calls into a library-wide ownership claim that can
fail. That placement was hiding a defect: game.c raises AKGL_ERR_SDL
when SDL_CreateMutex fails, five lines before akgl_heap_init ran, so the
earliest error path in the library was guaranteed to print "Unknown
Error". akgl_error_init is now the first statement in akgl_game_init.

Callers that drive subsystems directly must call akgl_error_init first;
it is idempotent, so ordering it precisely is not required. The eleven
test suites that relied on akgl_heap_init to name their statuses now
call it explicitly, or their failure messages would have degraded to
"Unknown Error".

Add tests/error.c: assert every code reads back its registered name,
that the name table and AKGL_ERR_COUNT agree, that a foreign owner is
refused with AKERR_STATUS_NAME_FOREIGN and AKERR_STATUS_RANGE_OVERLAP,
and that repeating the init is a no-op. That last one is a live
constraint, not a triviality -- libakerror treats only an identical
reservation as a repeat, so a subset or superset raises.

28bde4176d Reindent all C sources to the canonical stroustrup style
Mechanical whitespace-only change across src/, include/, tests/, and
util/, applied with scripts/reindent.sh. No behavioral change.

Most files already conformed. The genuine outliers indented at 2 columns
(json_helpers.c, util.c from akgl_rectangle_points onward, assets.c,
staticstring.c, akgl_actor_add_child, util.h, staticstring.h) or used
spaces where the canonical form is a tab (draw.c). cc-mode also re-aligns
line-continuation backslashes in multi-line macros to its default
c-backslash-column, which is required for the tree to be a fixed point of
the indenter.

Verified whitespace-only: `git diff -w` over this change is empty apart
from three trailing blank lines removed at EOF in src/heap.c,
src/registry.c, and tests/tilemap.c. The build produces no new errors and
ctest is unchanged at 13/14, with `character` still the one intentional
failure.

The tree is now a fixed point of `scripts/reindent.sh --check`.

include/akgl/SDL_GameControllerDB.h is generated and excluded.

22162db2da Add physics, heap, json_helpers, game, and actor test suites
Raise line coverage from 39.6 to 61.8 percent with four new suites and an
extension to the actor suite, and register every suite through a single
CMake list so a new test file cannot be left out of the coverage fixture.
Give the test targets a build-tree RPATH and prepend the build tree to
LD_LIBRARY_PATH for CTest, so a developer with a previously installed
libakgl.so exercises the library that was just compiled.

Fix six defects the new tests exposed:

- akgl_physics_simulate read self->gravity_time before its NULL check, so a
  NULL backend crashed instead of reporting AKERR_NULLPOINTER.
- akgl_game_save transposed CLEANUP and PROCESS, which placed the fclose
  inside the PROCESS switch. An ordinary save never flushed or closed its
  stream and produced an empty file.
- akgl_game_save_actors wrote each name table terminator from the address of
  a single char, emitting stack contents into the save file and a sentinel
  the loader could not recognize.
- akgl_game_load_objectnamemap used CATCH directly inside while(1), where the
  break leaves the loop rather than propagating, so a truncated name table
  loaded as a successful game.
- akgl_Actor_cmhf_up_on and _down_on dereferenced actor->basechar with no
  NULL check, unlike their left and right counterparts.
- akgl_actor_logic_movement checked actor twice instead of checking
  actor->basechar before dereferencing it.

549b27d3eb Document the libakgl API with Doxygen
Add file, structure, global, and function documentation across all libakgl-owned headers and sources, including parameter contracts and likely AKERR/AKGL_ERR exceptions. Add a strict Doxyfile and build the generated API documentation in Gitea CI with warnings treated as failures.
