Fix review findings: importer DoS, sync data loss, views/profile rendering, docs

Source importers: lstat before open so FIFOs no longer hang the directory
walk; replace the quadratic Rust macro regex with a linear scan.
Three-way sync: report page add/add and delete-vs-modify as conflicts
instead of silently overwriting or resurrecting; canonical comparison so
key order is not a change; the sync action withholds output and fails on
conflicts unless --force. Story publishing escapes <, >, & and U+2028/9
inside the embedded JSON.
Views: drop parentId of unselected containers, re-layout instead of
manual geometry, validate before serialising; flatten() merges identical
nodes repeated across pages so C4 output works with every analysis
action. Dark theme edge labels get a background; tube-map corridors sit
above the stations; C4 containers keep the swimlane style and orphan
relationships land on the matching page; router keeps container header
bands as obstacles; sequence self-messages loop on one side.
Docs: SKILL.md lists all 23 CLI actions and how each capability family
is invoked, task wrappers for query/test/what-if/doctor, capability
tables and --page scope corrected, maintenance snippet uses the real
synchronous action signature, duplicated rule bullets moved to the rule
references, coverage matrix wording made verifiable.
