ini.nx

ini.nx -- parse INI-style configuration files. Classic [section] / key = value format. Simpler than TOML, used by 30+ years of Windows config + a lot of C daemons (php.ini, systemd unit files, mumble / xmms / qt config). Format: [section_name] <- section header, any leading/trailing ws ok key = value <- key/value, '=' or ':' separator ; comment <- semicolon # comment <- hash (blank line) We return a flat array of (section_off, section_len, key_off, key_len, val_off, val_len) tuples. The section fields are zero if a key appears before any [section] header. Like query.nx, this is zero-alloc -- we emit offsets into the caller's buffer and never copy. Whitespace around keys/values is trimmed (not stored). Inline comments are NOT supported (value runs to end-of-line). Invariants: I1 Empty input -> zero entries. I2 Keys with no '=' or ':' are silently dropped (warning would be logged in a production parser; we stay quiet). I3 Sections persist down until next [section] header. I4 Duplicate keys: all are emitted; caller picks which wins.
