The vault holds the target's prior values so a bad rotation can be undone
— the one place raw credentials touch disk. It was written as plain JSON
at mode 0600, and a permission bit is all that was protecting it. That
stops another user on the same box. It does nothing about a backup, a
synced home directory, a lifted disk, or any process running as the
owner, and those are the cases where a credential store is worth reading.
Each run is now sealed to this machine's identity: a fresh DEK per write,
the payload sealed with it, the DEK sealed to the identity public key. So
the file opens with the secret key in identity.json and nothing else. The
key names go inside the ciphertext along with the values — knowing that
an endpoint holds STRIPE_LIVE_KEY is worth something by itself.
A DEK per run rather than one for the store: reusing a key would make a
single compromise open every rollback ever captured, and there is nothing
to gain by it, since the wrapped DEK travels in the file.
Plaintext vaults written before this still open. Refusing them would
strand the rollback data they exist to hold, and a vault reader that
cannot read yesterday's vault takes away the thing the vault is for.
The store's vault methods become async, which the three callers in the
engine already sat inside async functions to accommodate.

New @logicsrc/plugin-credential-sharing: a provider-neutral secret-sync engine
with env/.env, Doppler, Railway, and GitHub Secrets adapters behind one
CredentialProvider contract.
- engine: inspect -> diff -> plan -> approve -> sync -> rollback -> audit/export
- dry-run is the default for sync; --approve writes; destructive changes gated
- fingerprint-based diffs (salted SHA-256); raw values never printed or stored in
plans/runs/audit; rollback pre-image kept in a 0600 .logicsrc vault (gitignored)
- github-secrets is write-only for values (sealed-box via libsodium), so it cannot
be a sync source or value-restoring rollback target
- CLI: real `logicsrc credentials <providers|inspect|diff|plan|approve|sync|
rollback|audit|export>` (replaces the prior stub)
- 4 JSON schemas registered in @logicsrc/validators
- flip logicsrc.com/credential-sharing band from coming-soon to available
- 37 tests pass; full env->env lifecycle verified; artifacts schema-validate
