feat(resolve): lower surviving blocks into targets and rule instances
...
Expands globs, resolves use edges between targets, propagates inherited
includes, and instantiates a rule once per matched input.

feat(eval): evaluate statements in written order
...
Expands variables top to bottom, runs checks as they are reached and evaluates
conditionals against results already established. Written order is the
semantics, not an implementation detail.

feat(configh): generate a guarded C header from probe results
...
Emits the project name and the HAVE_ and SIZEOF_ defines from what the probes
actually found, behind an include guard derived from the output path.

feat(probe): detect headers, functions, symbols, sizeof and pkg-config
...
Compiles and links throwaway programs to answer each check, and shells out to
pkg-config for cflags and libs. Results are memoised on the toolchain.

feat(exec): spawn subprocesses and capture stdout and status
...
Argv-vector execution with no shell in the path, so arguments containing
spaces or quotes need no escaping.

feat(parse): parse the grammar with recursive descent
...
Turns tokens into the AST, and consults suggest at each failure point so an
unknown declaration or field offers the nearest valid name.

feat(ast): model statements, blocks and nested conditionals
...
Keeps written order, so a later branch can observe the result of a check that
appeared earlier in the file.

feat(lexer): tokenise build files with a span on every token
...
Words, strings, braces and comments, each carrying its source range, so an
error points at the offending token rather than the whole line.

feat(types): define resolved project, target and rule records
...
Targets carry sources, includes, flags and uses; rule instances carry resolved
inputs and outputs. This is the shape every later stage consumes.

feat(suggest): rank near-miss names by edit distance
...
Levenshtein with a cutoff, returning the closest valid name at a position, or
nothing when no candidate is close enough.

feat(json): emit JSON with correct control-character escaping
...
So generated output survives paths containing spaces, quotes or backslashes.

feat(glob): expand source patterns without shelling out
...
Matches *, ? and ** against directory entries directly, so src/**/*.c
resolves identically regardless of the shell.

feat(fs): add recursive mkdir, whole-file IO and mtime reads
...
Path joining, read, write, is_dir and mtime, used by every later stage that
touches disk.

feat(ident): normalise names into C macro identifiers
...
Uppercases, replaces non-alphanumerics with underscores, and derives the
HAVE_X and SIZEOF_X forms the generated header uses.

feat(diag): render errors with a caret and the offending line
...
Formats file:line:col, re-reads the source to print the line, underlines the
span and leaves a slot for a suggestion.

feat(style): gate ANSI colour on tty detection
...
One wrapper per colour plus a padding helper, all no-ops when stdout is not a
terminal, so piped output and CI logs stay readable.

feat(span): track byte ranges so errors can point into source
...
Span.t carries file, offset and length, with join to merge two spans and a
none sentinel for synthesised nodes. Every token and node gets one.

The meow library against unix, plus ignore rules for _build, generated
sources and the meowc symlink.
