Restrict bypass to LIMIT/OFFSET/FORMAT/SETTINGS to preserve trailing-comma-before-keyword-table handling

Address review feedback: previous lookahead applied to all clause-starter
keywords, which regressed parsing of `SELECT a, FROM `limit`` (trailing
comma before FROM where the next ident is itself a clause keyword).
Restrict the special-case to the four keywords that legitimately appear
as bare column names. FROM/WHERE/GROUP/ORDER/etc. stay unconditional
terminators so PR #268 trailing-comma handling is preserved.

Adds regression fixture select_trailing_comma_before_from_keyword_table.sql.
