Protondrive CLI 0.2.3

This patch release fixes rclone configuration for Proton accounts that use a separate mailbox password.

Highlights

• Added --mailbox-password and --mailbox-password-stdin for rclone-backed configuration.
• Passes mailbox_password to rclone using rclone-obscured secret values.
• Stores the optional mailbox password in the encrypted credential vault when --store-credentials is used.
• Reuses the mailbox password during credential-vault refresh.
• Documents stdin ordering for headless two-password accounts.
• Leaves local_path out of configure; sync local paths remain handled by positional args or JSON sync configs.

PR / issue triage

• The relevant part of PR #4 was implemented cleanly in main.
• PR #4 was not merged because it included unrelated local_path configuration changes, a credential debug print, and no tests.

Validation

• Verified rclone provider metadata exposes mailbox_password for Proton Drive and does not expose local_path.
• go test ./...
• go vet ./...
• Local rclone-config smoke test with fake credentials and --mailbox-password-stdin
• Linux builds for amd64 and arm64
• macOS builds for amd64 and arm64
• Archive checksum verification
