sickn33 3efff111d2 fix(security): Harden skill tooling file handling
Guard metadata repair and doc sync scripts against symlink targets so
repo maintenance tasks cannot overwrite arbitrary local files.

Replace recursive skill discovery with an iterative walk that skips
symlinked directories, and harden the VideoDB listener to write only
private regular files in the user-owned state directory.

Also fix the broken pr:preflight script entry and make the last30days
skill stop embedding raw user arguments directly in the shell command.
