Windows PowerShell 5.1's -Encoding UTF8 always prepends a BOM, and
Get-FileHash returns uppercase hex. Bash's manifest reader expects neither,
so a manifest written by this module and later read by the Bash
equivalent (or vice versa) mismatched on every single entry: the BOM
folded into the header's first field, and every hash comparison failed on
case alone. Hashes are now lowercased on read and write, and the manifest
file itself is written UTF-8 without a BOM.

Adds Sync-ManagedDestination and its manifest helpers: a per-destination
TSV of path -> SHA-256 that makes installation idempotent (unchanged files
are neither rewritten nor backed up), detects files this setup previously
installed that the source no longer ships (removed after backup, unless
changed locally, in which case they are backed up and left in place with
a warning), and never touches a file it never installed. Backups for a
run land together under backups/<stamp>/ instead of one suffix per file.
