feat: async/await/spawn + fix else-if lowering bug
...
Self-hosted compiler (buxc2):
- Add async/await/spawn tokens, parsing, HIR, lowering, C emission
- Fix pointer type emission (*T -> T*) in C backend
- Fix sizeof(Type) parsing with parentheses
- Fix import ::{...} infinite loop guard
- Fix int64 emission by avoiding else-if chain workaround
- Add debug-free cli and hir_lower
Bootstrap compiler (Nim):
- Fix critical else-if lowering bug in hir_lower.nim:
when both elseIfs and else block exist, elseIfs were dropped
causing all else-if chains to collapse to if+else only
Runtime:
- Fix bux_async_await memory corruption (don't free in run)
- Add bux_remove_from_ready for safe cleanup
- Fix forward declaration and deduplicate bux_now_ms
Docs & examples:
- Update async.bux example with proper int64 params
- Update README, LanguageRef, Stdlib, PLAN for async features
- Mark Phase 7.10 bootstrap loop as completed
All 27 examples pass. buxc2 check/build work on all examples.

Phase 7.10: multi-file project build, module braces, else-if fix, UTF-8 lexer
...
Runtime (stdlib/runtime.c):
- bux_list_dir() — directory listing with extension filter
- bux_run_cc() — invoke C compiler on generated C code
- bux_mkdir_if_needed() — create build directory
- bux_dir_exists() — check if directory exists
- Removed duplicate bux_path_join
Parser (src_bux/parser.bux):
- Module parsing with braces: module X { ... }
- else-if parsing: wraps inner if in synthetic Block
- Infinite-loop safeguards in module body and struct body parsing
Lexer (src_bux/lexer.bux):
- lexPeek: mask with & 255 to handle UTF-8 signed char bytes
CLI (src_bux/cli.bux):
- Cli_BuildProject(): multi-file build from src/ directory
- Lists .bux files, parses each, merges declarations inline
- Runs sema + HIR + C codegen on merged module
- Invokes C compiler to produce binary
- New extern declarations: bux_file_exists, bux_dir_exists, bux_path_join,
bux_mkdir_if_needed, bux_run_cc, bux_list_dir
- FileExists(), DirExists() wrapper functions
- "project" command dispatch
Known issue: else-if chain not fully emitted by buxc2 C backend
(lexSkipWhitespace missing comment handling in generated C).
All 18 examples pass, all unit tests pass.

Phase 7.9: Self-hosted compiler buxc2 builds and runs! 🎉
...
buxc (Nim bootstrap) successfully compiles buxc2 (Bux self-hosted compiler)
into a working 88KB ELF x86-64 binary.
Compiler fixes (Nim):
- duplicate symbol: user funcs shadow stdlib funcs via mergeDecls()
- forward declarations: func without body + definition (both orderings)
- extern func dedup: same extern in multiple files
- discard keyword: new language keyword, lowered to expr stmt or no-op
- parser: keywords as field names + advance-on-error safeguard
- parser: var without initializer (zero-init)
- parser: multi-line || && continuation expressions
- parser: else-if chain newline handling
- C backend: const declarations emitted as #define
- C backend: load(field_ptr) → base.field optimization (fixes lvalue errors)
Source fixes (src_bux/*.bux):
- types.bux: tk* → ty* prefix for type kind constants (avoid token conflict)
- sema.bux: remaining tk* → ty* references, StringMap → *void workaround
- hir_lower.bux: ekReturn removed, Lcx_LowerParam helper, *f dereference
- c_backend.bux: &mod.funcs[i] for pointer passing
- cli.bux: ReadFile/WriteFile → bux_read_file/bux_write_file wrappers
- parser.bux: pathStr.len → String_Len(pathStr)
- types.bux: "*" + x → String_Concat("*", x)
Build system:
- Makefile: added 4 missing examples + selfhost target
- PLAN.md: updated with actual project state, Phase 7.9 marked complete
All 18 examples pass, all unit tests pass.
