dsh-vault v0.8.4

v0.8.4 — pass export, redacted reads, batch get, import merge

• vault_export_wallet: pass-compatible .gpg files (standard Unix password manager)
• vault_get: redact param masks secret fields
• vault_get_many: batch read with a fields whitelist
• Bug fix: vault_import merges into existing entries (fills gaps) instead of skipping
• UI: recently-added list
