The fallback regex in email_pollers.py that recovers a
[{"action": ...}, ...] JSON array from raw model output used lazy
[^[\]]*? runs inside a (?:,\s*\{...\}\s*)* repetition, which backtracks
exponentially (CodeQL py/redos) on inputs like [{"action"},{ + }},{{ * N.
It runs on the LLM reply to an email→calendar prompt embedding the
untrusted email body, so a crafted email can stall the background poller.
Extract the pattern to a module-level _CAL_ACTION_ARRAY_RE and rewrite the
object-content class from the lazy [^[\]]*? to a greedy brace-delimited
[^{}], which removes the quantifier ambiguity. The match is linear (a 500KB
adversarial input now resolves in <1ms) and equivalent on well-formed
arrays; it is also strictly more robust for values containing '[' or ']'
(the old class bailed on those and extracted nothing).
Resolves CodeQL py/redos #198.
