Module key 

Parsing of UPPERCASE inference keys used in AIM prompts and responses.

Keys are UCIDs ([A-Z_][A-Z0-9_]*) with one of three suffix patterns:

• key_colon_eol: UCID ':' optional whitespace, then end-of-line → multi-line body follows.
• key_eol: UCID optional whitespace, then end-of-line → delimiter/marker line.
• key_colon: UCID ':' → inline value on same line.
