Add core.fmt.json — a complete RFC 8259 JSON library with recursive-descent
parser, serializer, builders, dot/bracket path accessors, and full cleanup.
Supports all 6 JSON value types plus JSON_ERROR for parse error reporting.
Numbers stored as Double via x87 FPU. Unicode \uXXXX escapes handled
(ASCII range emitted, non-ASCII replaced with '?').
Supporting changes:
- core.strings: add int64ToString, doubleToStr (scientific notation for
very large/small values, fixed-point for normal range, trailing zero
trimming), plus unit tests for both
- asuro.pas: wire core.fmt.json.UnitTest into the boot test suite
- mkdocs.yml: add JSON nav entry under Formats
- doc/src/core/fmt/core.fmt.json.md: full API documentation
- doc/src/core/core.strings.md: document int64ToString and doubleToStr
- doc/planning/json.md: implementation plan and design spec
- doc/planning/webgpu.md: WebGPU-over-WASM design plan (software
rasterizer backend for WASM apps importing webgpu.h)
Introduce core.panic, a new architecture-agnostic kernel panic engine
with a pre-allocated LVGL BSOD screen. The screen and all widgets are
created at init time so that zero LVGL allocation occurs at panic time.
Layout features:
- Top banner with decoded teapot TGA image (128x128) and title/subtitle
- Two-column content area with dark semi-transparent cards:
- Left: Fault Details, CPU Registers, Process Info, System Info
- Right: Call Stack (full height)
- Pastel red background (#7A2828), monospace text for data sections
Key changes:
- Add core.panic.pas with pre-built BSOD screen, register/trace/system
info formatting, hex conversion helpers, and syslog fallback
- Add arch.x86.panic.pas as the x86 bridge: packs interrupt registers
into a TRegisterSnapshot and calls core.panic.panic()
- Simplify all 19 x86 fault handlers to one-liner panic calls
- Remove legacy BSOD code from arch.x86.util.pas
- Add teapot.tga (256x256) embedded via splash_tga.asm
- Add LVGL bindings: lv_refr_now, lv_image_create, lv_image_set_src,
lv_image_set_scale, lv_image_set_inner_align, and style helpers
- Wire up panic init and test command in asuro.pas
Removes per-lookup heap allocation (MD5Buffer/kfree) in favour of a
single zero-allocation FNV-1a32 pass. Drops core.enc.md5 dependency
from core.ds.hashmap.
- core.enc.fnv1a: FNV-1a 32/64-bit non-cryptographic hash with UnitTest
- core.enc.djb2: DJB2 XOR/Add 32/64-bit hash variants with UnitTest
- core.ds.bloom: probabilistic bloom filter (Bloom_New/Add/Test/Clear/Free)
using double hashing (FNV-1a32 + DJB2_32) with UnitTest
- core.ds.types: add TBloomFilter / PBloomFilter record
- asuro.pas: wire all three UnitTests into boot test suite
