Add "one vault, synced everywhere" for PC + Ubuntu laptop + phone, with an
identical flow and no stored master password. keepass-open prompts the master
password (in memory only), folds in strays, pulls+merges the cloud copy over
WebDAV, opens KeePassXC on ~/Keepass/Passwords.kdbx, and publishes edits on
close. Safety rests on `keepassxc-cli merge` (entry-level union) plus a dufs
?hash compare-and-swap on upload, so concurrent edits merge instead of clobber.
The consolidator enforces exactly one vault per machine: it folds a stray only
if it opens with the same master password, backs up first, never removes the
canonical, and auto-excludes the dufs serve-path (the remote store) — a
data-safety fix after the first real run tried to delete ~/cloud/Keepass.
Only the dufs *server* password (not the vault key) is cached in the keyring.
Single cross-distro installer, no role flag; the phone uses KeePassDX natively.
Verified: shellcheck clean; 8 (reconcile) + 14 (consolidator) + 8 (installer)
assertions on throwaway vaults; real PC apply with live WebDAV GET=200 and
?hash==sha256; a clean keepass-open run ("no strays / already in sync").

# Flow (the master password lives only in this process's memory):
|

# 1. prompt for the vault master password

# 2. consolidate any stray *.kdbx on this device into the one canonical vault
|

# 3. reconcile with the cloud (pull remote + merge + push local) — bidirectional

|

# 5. on close, reconcile once more so this session's edits are published
