Hermes delivery layer truncates cron output at MAX_PLATFORM_OUTPUT (4000
chars) unless the adapter advertises splits_long_messages=True. Mark the
Nextcloud Talk adapter as such and implement word-boundary chunking in
send() and the standalone path, splitting content over 10000 chars into
multiple Talk messages with unique reference ids (Nextcloud dedupes on
referenceId, so a per-chunk suffix is required to avoid drops).

Verified end-to-end against nc.hoyer.xyz: a 59,582-char payload was
delivered as 6 Talk messages (ids 33286-33291), all under the 10000
limit.
