New features

REPEAT [<target>] EVERY <interval> [FOR <duration> | COUNT <iterations>] [TO <file> [AS CSV|JSON|TEXT]] runs the last query, a BEGIN ... END block of queries, an @script or a LIB RUN script again and again in the foreground until Ctrl+C, COUNT or FOR; durations are a whole number followed by s, m or h; only queries can be repeated; TO appends each iteration with its timestamp

DESC <table> ALPHA (also DESCR, DESCRIBE) lists the same columns sorted by name, ignoring case; without ALPHA the table order is unchanged, and any other text after the table name is now refused

DUMP ... AS H2, AS XLSX and AS ODS accept MODE APPEND (no KEY): the rows of any query, joins included, are added to an existing table or worksheet with the same columns, names and order; types are not compared, a mismatch writes nothing
the Connections Definition File ($CDF), or any connection opening the same database file, is refused as a DUMP, PULL or EXPORT destination

Console: Ctrl+C pressed as a query is being sent is no longer missed, / <environment> reruns can be cancelled, and a Ctrl+C that stops a statement on BroadSQL's side keeps pending changes
Console: Ctrl+C during a running query, script or REPEAT stops only that work and keeps BroadSQL open with the JLine console (it could close BroadSQL)
Console: a TAB in pasted or indented SQL stays a TAB; TAB completes only a word being typed, lists the candidates after a space without inserting one, and never inserts a keyword such as ALL

No special steps required for this release.
