dimgigov 6744a35c03 Phase 7.10: workaround else-if bug in lexSkipWhitespace 
Lexer (src_bux/lexer.bux):
- Rewrote lexSkipWhitespace to use nested if/else instead of else-if
  chain (workaround for Nim C backend else-if lowering bug)
- lexPeek: mask with & 255 for UTF-8 signed char bytes

Known: buxc2 project build hangs on ast.bux parsing (infinite loop).
buxc2 single-file build works correctly with else-if.
All 18 examples pass, all unit tests pass.

dimgigov 74117595d2 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.
