Subject: [PATCH] =?UTF-8?q?fix:=20strip=20all=20accumulated=20tags=20in=20?=
 =?UTF-8?q?stripTagPrefix=20to=20prevent=20=C2=A7N=C2=A7=20accumulation?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The TAG_PREFIX_REGEX was only matching a single tag prefix, causing tags
to accumulate when content is processed multiple times during transform
passes, compartment compaction, or message replay.

Changed the regex from /^§\d+§\s*/ to /^(?:§\d+§\s*)+/ to match one or more
consecutive tags at the start of the string. This ensures stripTagPrefix
removes ALL accumulated tags before prependTag adds a fresh one.

Fixes #11
