Problem
Single-char tokens (, ), [, ], {, }, <, >, ,, =, ., :, @, ~, #, \n\ each heap-allocate and copy a 1-byte string. They dominate token count.
Location: \src/lexer.c:162-177\ (\make_token)
Proposed Fix
Add ownership flag to \Token. Use static literal pool for single-char tokens. \ oken_free\ skips \ ree\ for \TOKEN_LITERAL_STATIC.
Status
Baseline still present — \make_token\ at \src/lexer.c:162-177\ still does \safe_malloc\ + \memcpy\ for every token. No ownership flag in \Token\ struct at \src/token.h:59-64.
